Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fried Frogs' Legs
Ingredients
Directions
Marinate
Marinate the frogs' legs in oil, vinegar or lemon juice, salt, and pepper for 3 hours.
Make the batter
Prepare the fritter batter by mixing flour, egg yolk, lemon juice, and oil.
Add enough wine to create a batter consistency.
When ready to fry, beat the egg white and fold it into the batter.
Fry
Dip the marinated frogs' legs in the batter and fry in hot lard for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the body of the batter that coats and crisps around the frog legs.
- Egg white
- Whipped and folded in, it adds air that makes the batter lighter and crisper.
- Egg yolk
- Adds richness and helps bind the batter so it clings to the legs.
- Vinegar or lemon juice
- Acid in the marinade tenderises the meat and brightens its flavour.
The step that matters
Folding in the beaten egg white. Folding gently keeps the air bubbles from the whipped white intact. Overmixing deflates them, leaving a denser batter that fries heavier.
