Preheat the oven to 200°. In a medium saucepan of boiling water, cook the garlic cloves over moderately low heat until they become very tender, about 25 minutes. Drain the cloves and pat dry. In a small bowl, mash the garlic to a smooth paste. Season with salt and nutmeg.
Line a baking sheet with parchment paper. Using a metal spatula, spread the garlic paste on the paper in two 6-by-4-inch sheets. Bake until crisp, about 1 hour. Let cool. Slowly and carefully peel the garlic wafers off the parchment paper and quarter to make 8 pieces.
The garlic wafers can be stored overnight in an airtight container. Serve at room temperature or recrisp for a few minutes in a 325° oven.
