How to cook chestnuts (2024)

How to choose chestnuts

Look out for chestnuts that are plump and heavy for 
their size, with taut, shiny brown shells. Give them a squeeze. If the shells cave in, they’re probably past their best. Cooking and peeling them is a labour of love, but worth the effort 
for the superior flavour.

How to cook chestnuts

Cut a cross in the rounded, shiny side of each nut, then either roast them cut-side up at fan 200°C/gas 7 for about 15 minutes until the skins start to curl away from the nut inside, or boil in a pan of water for about 10-20 minutes until tender.

Next, break away the shell and remove the papery brown membrane, which is easiest while the nuts are still warm. The boiling method is best if you want to turn them into a purée or sweet paste. The roasting method produces a drier nut and is better for soups, stews, stuffing mixtures, cakes and biscuits.

How to forage for chestnuts

Sweet chestnuts, not to be confused with horse chestnuts or conkers, grow wild. They’re easily recognisable by their large, elongated, pointed leaves, which are heavily veined on the underside and have coarsely serrated edges. They’re one of the first leaves to turn golden as autumn gets underway and the nuts are ready to eat when they fall to the ground.

The actual nuts are protected by a spiky casing, which you need to remove first. British chestnuts are smaller than their Italian, French or Spanish cousins (which are the ones most widely available in our food shops), but in a good year, they’re plentiful – if you can get to them before the squirrels do, that 
is – and full of flavour.

When to eat chestnuts
