There’s a bakery near my house in Boston that makes a quiche with the most wonderful smooth and creamy filling. Every time I ask the owner for her recipe, she shrugs and says something about having made it this way forever. She has no intention of telling me more.
But I figured it out! If you want an exceptionally creamy filling in quiche, use all heavy cream.
