Step 1

Peel and finely slice 1kg Jerusalem artichokes, adding to a bowl of water and lemon juice. Heat 75g butter in a large frying pan over a medium heat and, once foaming, add the artichokes, 1 crushed garlic clove and 3 thyme sprigs.

Step 2

Cook for 20 mins or so, adding another 75g cubed butter gradually, cube by cube, basting frequently so that the artichokes are always covered in foaming butter, until they’re a rich roasted colour. Just before serving, toss with the juice 1 lemon and season to taste.
