Ingredients
Directions
Make the base
In a saucepan, melt the butter over medium heat.
Add sugar, water, and grated lemon; bring to a boil.
Stir in flour until thickened and raw flour taste disappears.
Remove from heat and mix in the eggs until well combined.
Spread mixture on a large dish and cut into small pieces.
Fry and serve
Heat oil in a frying pan until tepid.
Fry the pieces slowly until golden, then drain on a soft cloth.
Dust with powdered sugar and serve.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the mixture and cooks out its raw taste, giving the pieces body.
- Eggs
- Bind the mixture and set as it cools, giving the pieces structure.
- Butter
- Adds richness and fat, contributing to tenderness and flavor.
- Sugar
- Adds sweetness and helps the fried pieces brown to a golden color.
The step that matters
Fry the pieces slowly until golden. Oil that is too hot browns the outside before the inside cooks through, while slow frying lets the interior heat evenly and dry out gently.
Swap the lemon
