French Crullers

Ingredients

Directions

Make the dough

  1. Rub together the melted butter, salt, and sugar in a bowl.

  2. Add the well-beaten eggs and milk, mixing until combined.

  3. Gradually add flour until the dough is thick enough to roll out.

  4. Roll the dough to ½ inch thick and cut out shapes with a small cake cutter that has a hole in the center.

Fry

  1. Fry the cutouts in hot lard until golden brown.

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

What each ingredient does

Eggs
Bind the dough and add richness and structure as they set in the frying fat.
Flour
Thickens the mixture so it can be rolled out and hold its cut shape.
Butter
Adds fat for tenderness and rich flavor in the dough.
Sugar
Adds sweetness and helps the crullers brown in the hot fat.

The step that matters

Frying the cutouts in hot lard until golden brown. If the lard is not hot enough, the dough absorbs fat and turns greasy and heavy; if it is too hot, the outside browns before the inside cooks through. Steady, moderate heat gives a crisp exterior and a cooked center.
