Butter each quiche pan.
Put pie crust in each individual pan. You can use one large pan to make one quiche instead of individual. In that case, double your filling ingredients.
Clean leeks. Cut off stem, slice thinly.
Saute leeks in butter just until softened, not browned.
Preheat oven to 400 degree F.
Wrap the corn in wet paper towel. Microwave for two minutes. Cool. Cut corn off cob.
Beat eggs with cream, salt, pepper. Add in cheese.
Pour eggs into each pie shell. Add corn and leeks evenly.
Bake for 15-20 mins until light golden brown.
