Step 1: Cook spinach
In a large pot of rapidly boiling salted water, cook 2 pounds (or two 10-ounce bags) fresh spinach for 1 minute.

In a large skillet cook 1/2 cup chopped onion and 2 to 3 minced garlic cloves in 2 tablespoons hot butter about 5 minutes. Stir in 1 cup whipping cream, 1/4 teaspoon nutmeg, and salt and black pepper to taste.
Step 4: Add spinach and cook
Bring onion mixture to boiling; cook, uncovered, until cream begins to thicken. Add spinach. Simmer, uncovered, about 2 minutes or until thickened. Season to taste with additional salt and pepper.
