In a small bowl combine milk, butter, lemon peel, vanilla, and egg; blend well. Add to dry ingredients all at once; stir just until dry ingredients are moistened.
Fill each paper-lined muffin cup with 1 heaping tablespoons of batter. Spoon half a teaspoon of jam into each cup. Spoon 1 heaping tablespoon of batter onto of the jam. Top with reserved chocolate and pistachios.
