Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the gluten network that gives the dough its structure.
Butter
Adds fat and richness, and creaming it with sugar traps air for tenderness.
Lard
Adds fat that keeps the crullers tender and short in texture.
Eggs
Bind the dough, add moisture and richness, and help set the structure.
Sugar
Adds sweetness and helps tenderize the dough when creamed with fat.

The step that matters

Frying in hot oil until golden brown. If the oil is too cool, crullers absorb excess oil and turn greasy; if too hot, the outside browns before the inside cooks through. Steady oil temperature gives even colour and a crisp, light result.
