Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Crullers
Ingredients
Directions
Make the dough
In a pot, combine the milk and water with the lard and bring to a boil.
Sift the flour and stir it into the boiling mixture, then remove from heat.
Let the mixture cool slightly, then work in the eggs until the mixture is firm but not too soft.
Shape and fry
Transfer the dough to a piping bag fitted with a large star tip.
Pipe rings onto greased parchment paper the size of your frying pan.
Carefully drop the rings into hot oil for frying.
Remove the parchment paper after a short time and turn the crullers several times until golden brown.
Finish
Once cooked, ice with vanilla icing.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Forms the starch structure that holds the dough together and lets the crullers puff.
- Eggs
- Add moisture and structure, helping the dough set firm during frying.
- Lard
- Adds fat for tenderness and richness in the choux-style dough.
- Milk
- Provides liquid and milk solids that add flavor and help browning.
The step that matters
Working in the eggs. Eggs must be added to a cooled mixture so they do not scramble, and the dough must be firm but not too soft. Too-soft dough will spread and fail to hold its ring shape in the hot oil.
