What each ingredient does

Thick sour cream: Provides moisture and a tangy richness that gives the filling a creamy body.
Powdered sugar: Adds sweetness and dissolves smoothly into the cream for a fine, even texture.
Blanched almonds: Add body, texture and nutty flavor, and a little fat to the filling.
