Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Batter for Timbale Cases or Fontage Cups
Ingredients
Directions
Make the batter
Combine egg yolks, water, salt, olive oil, and flour in a bowl to make a thin batter.
Let the batter stand for 2 to 3 hours before using.
Fry the timbale
Heat a kettle of fat until it smokes.
Dip the hot iron mold into the fat to heat it.
Wipe off excess fat from the mold.
Dip the mold into the batter to coat.
Return the coated mold to the hot fat.
Cook until golden brown.
Drain the mold on soft paper.
Avoid touching the bottom of the kettle.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Egg yolks
- Add richness and help bind the batter so it coats the mold and sets in the fat.
- Flour
- Forms the body of the thin batter that becomes the crisp shell when fried.
- Olive oil
- Adds fat that contributes to tenderness and helps the shell brown evenly.
- Water
- Thins the batter to a coating consistency so it spreads thinly over the mold.
The step that matters
Coat the mold and return it to the hot fat promptly. The batter must set and brown quickly on contact with hot fat. If the coated mold cools or sits before returning to the fat, the batter can slide off or absorb excess fat, giving a greasy, uneven shell.
