This recipe from Viktoria’s Table is one that she makes with either potatoes or sunchokes. Ours are not as large as the one in the picture (ours must be a different variety), but by slicing then length ways you should be able to get large pieces to make this recipe with.
You will need:
1lb Jersalem Artichokes
1tsp olive oil
salt and pepper
2Tbsp butter
2 garlic cloves
2-3 tsp dill
a handful of crumbled feta
