Ingredients
Directions
Make the paste
Combine butter, sugar, water, salt, and lemon rind in a saucepan. Bring to a boil.
Remove from heat and discard the lemon rind. Gradually add flour while stirring continuously.
Return to heat and stir for 5 minutes until the mixture pulls away from the sides.
Transfer to a bowl and add eggs one at a time until the paste is sticky.
Shape and bake
Butter and flour a baking sheet. Shape the paste into walnut-sized balls.
Insert blanched almonds into each ball and brush with egg yolks.
Dust with powdered sugar and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides structure, setting the paste so the balls hold their shape while baking.
- Eggs
- Add moisture and structure, and make the paste glossy and sticky enough to pipe or shape.
- Butter
- Adds fat and richness, contributing tenderness and flavor to the paste.
- Sugar
- Adds sweetness and helps the baked surface brown.
The step that matters
Adding the eggs. Eggs must be added one at a time and the paste beaten until smooth and sticky. Adding them too fast can make the dough split or stay loose, and the balls may spread or fail to puff in the oven.
