2 large leeks (white and light green parts only), halved and thinly sliced
3 large eggs
3/4 cup milk
1/2 cup all purpose flour
a spoonful of grainy mustard (1 tsp - 1 Tbsp)
1/2 tsp. sugar
salt and pepper to taste
1 cup shredded Gouda
1Preheat oven to 450°F. In a large ovenproof (cast iron works great!) skillet, cook the bacon until crisp. Set aside, pouring off all but a couple spoonfuls of the drippings. Cook the leeks in the pan for 5-8 minutes, until soft and turning golden.
2Meanwhile, whiz together the eggs, milk, flour, mustard, sugar, salt and pepper in a blender or food processor until smooth.
3Scatter bacon over leeks in the skillet and pour the batter overtop; sprinkle with cheese. Bake for 10-15 minutes, until slightly puffed and golden. Cut into wedges and serve warm.
