Make the pancake batter by beating the eggs, flour, milk and salt together and leave half an hour. You can use a mixer/processor for this if you want.

Make your pancakes and keep them warm until you have your filling ready.

Melt the butter in a pan and gently fry the onions or shallots until soft but not browned.

Add the chopped mushrooms and fry gently for another ten minutes.

Remove pan from heat and add two tablespoons of thick cream to the pan, mix well and add salt and pepper to taste.

Add the mustard, if preferred, at this stage, to spice up the mixture.

Take each of your pancakes and put a slice of ham and then a tablespoon of the mushroom and onion mixture onto each one, roll up and place in a warm ovenproof dish.

Put some cream over the pancakes and sprinkle with grated cheese and bake for about ten minutes in a hot oven until cheese has melted and turned a golden brown.

Your Ficelle Picarde’s are now ready to serve.
