Japanese knotweed jam recipe


A delectably thick, fruity-flavoured jam which is gorgeous as a layer in Japanese knotweed frangipane or lathered onto toast. This is one of the recipes from my book: Wild and Sweet - forage and make 101 seasonal desserts.

If your not familiar with this as an edible wild food, I highly recommend it for flavour, health benefits and as a way to manage the spread of this invasive plant. Find out more about Japanese knotweed on these blogs; Eating Japanese knotweed and Tricks for making Japanese knotweed edible.

To make this recipe you'll first need to make a puree from the knotweed. This is an unembellished, unsweetened ingredient for cake, jam or savoury recipes. The leftover liquid is also perfect for making Japanese knotweed syrup.

I love using brown sugar for sweet and wild treats as it contributes more nutrients. It does also make a darker jam. If you prefer, you can add a squeeze of lemon juice before boiling the puree to help keep the colour.
