Simple and delicious (wild) onion-flavoured water biscuits. Serve with cheese or just plain on their own. I made these for a group of school children who loved them (phew!). They ate them plain and with wild herb butter on.

This recipe uses three-cornered leek (Allium triquetrium), but you could use any of the wild garlic family. Just follow these simple tips to make sure the biscuits work.

Water Biscuits with Three-Cornered Leek

For these to work you need wilted or slightly dried out three-cornered leek or wild garlic. To do this, pick a couple of days ahead and leave out to dry. You'll need to use the garlic/onion/leek leaves, not the bulb for this recipe. If you're using fresh leaves (and really cant wait) then crush and squeeze the plant to remove some of the fresh sap.

Makes 60-70

Recipe

  • 400 g plain flour
  • 1 tsp baking powder
  • 100 g butter, cubed and cold
  • Small handful of three-cornered leek, wilted (leave to dry out for a couple of days)
  • Large pinch sea salt
  • 120 ml (8 tbsp) water 

Preheat the oven to 180C/fan 160C/Gas 4. Grease 2 large baking trays. Finely chop the three-cornered leek (or wild garlic leaves). Blend the flour, baking powder, butter, three-cornered leek and salt into bread crumbs with your fingers, or in a food processor.

Gradually add the water to to make a soft dough, not sticky, not dry. Roll out onto a dry surface until as thin as possible, mine made a square of 50 cm x 50 cm, I cut the edges to make straight sides then re-rolled the leftovers and cut these too. Cut into squares or rectangles about 4-5 cm long/wide, sprinkle with water then slice off the surface and place on the baking tray.

Bake for about 15 minutes, till very slightly golden. Remove onto a cooling rack and leave them to harden a little longer. Store in an airtight container for up to 2 weeks. These are rather yummy on their own, or with wild herb butter, or I enjoyed with a Cornish brie!

I don't mind what you call it. In Cornwall and the Isles of Scilly this plant is often called wild garlic. Those who call it this know what they mean. They know they're talking about the onion grass, the long, thin one that smells of garlic. In Australia and New Zealand it's known as onion weed.

This blog is all about three-cornered leek, or whatever name you call it by. I describe its unique qualities, where it grows and how it compares to using wild garlic/ramsons (Allium ursinum) in recipes.

Three cornered leek is also in my Wild Food Foraging book and I regularly teach it on my foraging courses, especially in spring.

Three-cornered leek (Allium triquetrium) goes by many local names, but only one latin one. All the local names refer to its garlicky smell; onion grass, onion weed, wild garlic, three-cornered garlic, three-cornered onion or three-cornered leek. A member of the allium family it originates from the Mediterranean, Madeira, Canary Islands and North Africa.

It was originally introduced to the UK in the 18th century and the rest is history.

Why is it called three-cornered?

It has three-corners! A subtle triangle shape is visible when you horizontally cut a leaf and a clear triangular shape is visible on a cut flower stem. When not cut, a ridge is noticeable on the leaves, acting almost like a spine which makes the leaves more buoyant and upright.

Which parts can you eat?

You can eat all of this plant - the roots, flowers, flower buds, leaves and flower stems. Here in Cornwall I start eating it through winter when the leaves are greener and before the flowers start to show.

The Roots

Showing the roots of three-cornered leek

The roots of three-cornered leek are similar to spring onions though a little more watery and sweeter. Like leeks, they take a bit of time to clean up and remove the mud.

Remember that in the UK you need permission to dig up roots. However, I've never been refused permission to dig up these roots. People are often very grateful for me to take this plant away as it spreads really easily.

The Leaves

The leaves are the mildest part of the plant. Sometimes I cook them by sweating them down in a little oil or butter. They have a mild onion flavour this way.

The Flowers and Buds

The flowers and flower buds have a strong garlicky crunch. I love sprinkling them over salads and using them as an edible garnish. The buds are lovely pickled too. The flowers are white with a distinct green stripe on them.

Flower Stems

These are my favourite parts as they are the sweetest. I love chewing on them as I walk, they are one of my favourite spring walk snacks!

Wild Garlic

Three Cornered Leek v Wild Garlic

Wild garlic (Allium ursinum) is stronger, earthier garlic flavour. It has broad leaves and tends to grow in woodlands and near streams. It lends itself well to baking and cooking.

Three cornered leek (Allium triquetrium) is milder and sweeter in flavour. It likes to grow in warmer climates and thrives well in open spaces and hedgerows in Cornwall and the Isles of Scilly. It lends itself well to using raw, like spring onion.

I often think that if a plant is in abundance, consider it a gift. Here's a simple recipe which uses a handful of this wonderful, edible weed. You could also use wild garlic, aka ramsons (Allium ursinum) or any of the allium family that you have growing nearby. You can use the leaves, stems, flowers, seed-pods and roots.

TOP TIP: Three cornered leek is quite a watery plant in the height of spring, so it is good to mash it under a rolling pin, or mash it as you knead to ensure you don't have pockets of moisture in your bread mix. You may need a little less water because of this too.

Three-Cornered Leek Bread

You can use the stems, leaves, bulbs and flowers for this recipe to create a mild, onion flavoured bread. Remember you need permission to dig up the roots.

Ingredients

  • 200 g fresh three-cornered leek
  • 500 g wholemeal flour
  • Pinch of sea salt
  • 1 tsp quick yeast
  • 1 dessert spoon honey
  • 400 ml warm water
  • 1  tbsp olive oil

Wash the three-cornered leek thoroughly, removing any limp outer leaves, and, if using, the outer layer of the bulbs and roughly chop everything into 3 cm pieces. Preheat the oven to 200°C. Put the flour, salt and yeast in a large mixing bowl and stir. Add the three-cornered leek and stir in. Dissolve the honey in the warm water and slowly add to the flour mix. Stir in, adding the oil. Knead for 10 minutes, then shape, and place in a greased 1 kg loaf tin.

Cover with a clean cloth and leave in a warm place for 20 minutes, or until doubled in size. Bake in the oven for 40-45 minutes or until hollow sounding when tapped.

Here are some other posts for three cornered leek. Enjoy.

Here in Cornwall, three-cornered leek (allium triquetrium) is often called wild garlic. I don't have a problem with that. I enjoy local names, to me, I associate it with locals taking ownership of the plants, land and so-called weeds surrounding them and I see that as a good thing.

(Allium triquetrium has long, thin leaves and stems which are triangular shaped and drooping white flowers)

As I live in Cornwall, I use 'our' wild garlic a lot, though you could use the true wild garlic, ransoms (allium ursinum) instead. Actually, I suggest you use the wild version that is easily available to you, and don't worry about the rest.

For the last two years, I've had a quick chat with the Cornwall based chef, author and multi-restaurant owner Nathan Outlaw when he's come down to Penzance to do a book signing of his latest book at the brilliant The Edge of the World Bookshop. An immensly energetic though laid-back, hard-working, kind and talented chef he's always a pleasure to talk wild food with.

I now have Nathan's Everyday Seafood Book in my, very small, cookbook shelf and ocassionally flick through it for inspiration and recipe ideas. It's always the Sea Lettuce (Ulva lactuca) oil that stands out to me, partly because of its brilliant colour, of course because it uses wild food, and also because it is very simple and easy to make.

(Sea lettuce seaweed, ulva lactuca, looks as you would imagine - like lettuce)

I decided to have a go at my own version - because I'm me, and I like to tweak things, and because, well you can find Nathan Outlaw's seaweed oil recipe in his book (see link above), so I thought I'd offer something else here.

Flavouring an oil is a great way to capture a wild aroma long after its season has passed. This oil will continue to mature once in your store cupboard and I suggest using it within 3 months.

Both three-cornered leek (aka wild garlic) and sea lettuce seaweed are rich in nutrients and health giving properties, including vitamin C, B vitamins, iron and immune boosting goodness. Spring is the best time for wild garlic and sea lettuce is good in spring or summer, or used dried. Below I use rapeseed oil - I had it in my cupboard, and hey, it's local too!

Wild Garlic and Seaweed Oil Recipe

Drizzle over soup, bread, cheese on toast, use it to cook spanish omelettes or to fry eggs in. Basically you can use it raw or in cooking.

Ingredients

400ml cold-pressed rapeseed oil

1 handful sea lettuce, fresh or rehydrated from dried

Small handful of three-cornered leek

Drop the sea lettuce and three-cornered leek into boiling water for 30 seconds, remove and plunge immediately into ice cold water. Squeeze out all the excess liquid and blend with the oil. Store in a dark cupboard and use within 3 months.

Spring is exciting - a combination of warmth and light gets plants, animals and human-animals going. Sometimes, for me, too going. The term mad march hare feels too close to home for me, as I prance around the hedgerows picking wild greens as if there is no tomorrow, or as if spring won't last forever, which of course it won't. Lets face it, we've often being waiting a while for it to come too.

Many wild greens respond well to being plucked, for example when the tops of nettles are snipped off this stimulates more growth and leaf tops to grow. So below I've chosen 5 common wild foods that arrive every year, a plenty and are happy to be plucked, appreciated and eaten.

Here are my top 5 pick-ables (non-technical term :)) for this spring, I have loads of nuggets of information and recipes to share on each of them, though for now I'll keep it brief.

My Top Five Spring Wild Foods

1. Stinging Nettles Urtica dioica

Never under-estimate a common plant, believe me, nettles are a valuable food and we are lucky to have them. Their nutrition and versatility makes them easy to use (just avoid being stung) and they are (in my humble opinion and according to nutritional facts) better for you than spinach or cabbage.

2. Wild Garlic Allium family

The wild onion, garlic and leek family is vast and too large to go into here, though their commonalities include a wonderful garlic taste (and smell), anti bacterial properties and support for the heart. The whole of the plant can be used and it can be used raw or cooked - raw is stronger. It is one of the key edibles of spring.

3. Cleavers/Goosegrass Galium aparine

Cleavers spread. They grow up to 1 metre long and can be collected without a bag (let them stick to you). The leaves are a wonderful spring cleanser and support the urinary and lymphatic system, though best cooked to avoid the not so pleasant hairy texture when raw and use in small amounts. I like to just pluck the tops and sweat them with nettles in butter or oil.

4. Alexanders Smyrnium olusatrum

Writing this from the south coast of Cornwall, Alexanders are definitely on my list. Abundant and often considered an invasive (land managers around Bristol have also practically pleaded with me to pick and eat them too). Nutritious and versatile, if you just know how to use them and pick them early on in spring.

5. Common Sorrel Rumex acetosa

Sorrel sap is tart and lemony and at its best in spring, and once you get your eye in, you'll start to see it everywhere. Delicious added to so many savoury and sweet dishes, though don't eat too much as it contains oxalic acid which isn't good to eat in large amounts. A little is fine though.

So there you have it, my five favourite wild greens, and yes greens are best in spring. Next spring, maybe I'll share a different five, as there's always more to share.

It's deep December and I'm standing outside. Actually, there's 8 of us standing outside and waiting for the one that's gone astray. Once we're all congregated, we begin. There's something innately quiet about walking in Winter, as if all around us is sleeping, and in some ways it is. We walk together through this slumbering landscape, initially unaware of the life around us.

What can you forage in winter?

From as early as November, my forager eyes start to spot edible greens that are normally associated with spring. Alexanders, Nettle Tops, Three-Cornered Leek (locally known as Wild Garlic), Wild Cress and Mustard, Pennywort, Wild chervil, Gorse flowers and even Daisy leaves and flowers for salads and cooked dishes.

Although the nutrition of plants can be significantly increased in Spring, goodness can still be enjoyed from these plants through the winter months. In Cornwall, where we may lack in terms of nuts and berries (there are only a few forests & woodlands here) it is more than made up with coastal plants and, due to the mild climate, a great choice of edible greens right through winter. While other areas of the UK are below frost or snow, there are milder areas of Cornwall that offer valuable forage-ables.

The benefits of foraging in winter

What's more, foraging feeds the soul not just in winter, though every time of year. According to the  National Wildlife Federation's article; It's all in the dirt, the reason for this includes good bacteria in the soil that releases seretonin - the feel good hormone. This makes me feel even better about my muddy boots and dirty fingernails too!

In some ways, there's more to see in winter, without the distraction of hoards of people, beautiful, bright flowers, and sunsets to melt into. Instead, the offerings maybe more subtle - beige stems, low growing greens, and flowerless stems, though don't be tempted to dismiss these edible due to their humble winter personas.

Common Hogweed seed (Heracleum Spondylium), for example (below), may look like a dead seed-head, though within it lies delicious aromatic flavours for curries and many sweet dishes.

Hogweed Seed and Almond Thins

If you need it, use foraging as an excuse to get you outside, for that dose of daylight, fresh air and nature fix. Watching wintering birds, or rolling white horses of the waves, and returning with a handful of winter greens, it's hard for the soul not to be lifted, even if just a little. And if you're still not convinced and only yearning for the bright yellow sun of summer, then perhaps gorse is the only cure for you. Up on the moorlands of Cornwall, somewhere, you will always find the bright yellow flowers of gorse; an uplifting flower. According to Bach Flower Remedies gorse can offer you hope, when all hope is lost. I promise, summer will return.
