Ingredients
2-3 leeks, washed well and sliced into 2cm rings
110g butter, split into 40g and 70g
70g flour
100ml milk
150g Cheese, grated- mature cheddar works well, or experiment with other hard cheeses.
nutmeg, grated, about 1/4 teaspoon
salt and pepper
mustard (if you like)
Breadcrumbs- I like to use panko, but homemade breadcrumbs are very good too.
A little more grated cheese
