Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Crullers or Wonders
Ingredients
Directions
Make the dough
In a bowl, mix the eggs, melted lard or butter, and sugar until well combined.
Gradually add sifted flour until the mixture is very stiff and can be rolled out.
Shape
Roll the dough very thin, like pie crust, and cut it into squares measuring 3 inches long and 2 inches wide.
Make several slits lengthwise in each square, stopping ¼ inch from the edges.
Using your forefingers, twist through every other slit to create a decorative shape.
Lay the crullers edgewise on a board and dent them slightly.
Fry
Fry in hot lard until they are a light 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.
- Melted lard or butter
- Adds fat for tenderness and a rich flavour in the dough.
- Sugar
- Adds sweetness and helps the cruller brown in the hot fat.
- Sifted flour
- Forms the stiff dough structure that holds the shape during frying.
The step that matters
Fry in hot lard until light brown. If the fat is not hot enough, the crullers absorb grease and turn heavy; if too hot, the outside browns before the inside cooks through.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
