How do you grow the ingredients?

Apart from almonds for nuts and milk (described in the previous section), there are hazelnuts and walnuts that you could grow, plus sweet chestnut if your garden or plot is big enough for such a tree. Expect to wait around four years for your first crop.

Hazel (Corylus maxima) is hardy in zones 6-9 and can grow to a large tree, so prune to keep it within bounds. Grow filberts, cobnuts or hazel nuts as an open centred bush (imagine a wine glass with the branches around the bowl).

Walnut (Juglans regia) is hardy in zones 5-8. It can become a very big tree, so choose an early maturing/fruiting (often described as precocious) type and prune carefully.

Sweet chestnut (Castanea sativa) - choose marron types for their nuts - can be too big for most gardens, so again, choose and prune carefully. Sweet chestnut likes sandy, well drained soil and is hardy in zones 5-9.
