Clark's quiche is excellent served for breakfast with fruit, or at lunch or dinnertime with a salad. This recipe makes two 9-inch pies. The reason for this is because if you only make one you will hate yourself the next day when there are no leftovers. The quiche microwaves well the next day. In fact, most people say that the flavors have blended better on the second day... If in the strange case that you are filled up with one pie, this is a great gift to give a friend or relative, or if you are stingy...it freezes well with tin foil.
Ensure the thawed spinach is thoroughly squeezed dry; excess moisture will lead to a watery quiche. A cheesecloth can be very effective for this. Render the bacon slowly until truly crisp for optimal texture and flavor, then drain well to avoid a greasy end product. For a perfectly set quiche and to prevent a soggy bottom, consider blind baking your pie crusts for 10-15 minutes before filling. Distribute the fillings and cheeses evenly to ensure a balanced flavor in every slice. Do not over-whisk the egg mixture; combine just enough to emulsify. Allow the quiches to rest for at least 10 minutes after baking; this allows the custard to set fully, making for cleaner slices.
