Spinach Quiche - cooking recipe

Ingredients

3 small eggs
1 cup heavy cream
1 lb fresh spinach
salt (to taste)
fresh ground black pepper (to taste)
1 quiche pastry dough (recipe here #35153, or 1 single pie crust)
3/4 cup grated gruyere cheese (Swiss ok)
1 pinch mace
1 tablespoon butter

Preparation

Beat eggs; add cream, then beat again.
Wash the spinach under water, and remove all the stems, piling the wet spinach into a large pot, adding no water.
Cook over medium heat, turning and stirring, for 5 minutes; then drain thoroughly in a colander, squeezing the spinach dry.
Take a pair of kitchen scissors and snip the drained spinach into tiny pieces.
Season the spinach to taste with salt and pepper.
Line pie pan with pastry or crust; place spinach in crust, top with grated cheese, add cream, sprinkle with mace, then dot with small bits of butter.
Place pie pan on a cookie sheet and bake in a preheated 350 degree F oven for 40 minutes or until domed and light brown.
Cool 30 minutes before slicing and serving.
