Edible Uses

Edible Parts: Leaves  Seed  Seedpod
Edible Uses:

Leaves - raw or cooked[172, 177]. A hot cress-like flavour, they are used in spring and early summer, the young leaves are best[9]. Immature seedpods - a hot pungent taste, they are used as a flavouring[9]. Seed - used as a mustard-like flavouring[172]. The pungency of mustard develops when cold water is added to the ground-up seed - an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound. The reaction takes 10 - 15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme and produces a mildly-pungent but bitter mustard[238].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.
