Spinach Quiche

Preheat the oven to 400°F and set a rack in the middle position. Remove the pie crust from freezer and thaw until just soft enough to easily prick with a fork, about 10 minutes. Prick the bottom and sides all over with a fork (pricking about an inch apart). Bake until fully cooked and lightly golden, 10 to 15 minutes. (Keep an eye on it...if it puffs up while cooking, gently prick it with a fork so it will deflate.) Don't worry if the crust cracks while baking; see my note below on how to fix it before proceeding. Set aside and turn oven down to 325°F.

Heat the butter in a small skillet over medium-low heat. Cook the shallots until soft and translucent, about 8 minutes. Do not brown. Set aside to cool.
