Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Deviled Beef in Batter
Ingredients
Directions
Prepare the beef
Cut slices of underdone roast beef and marinate in vinegar, salt, and mustard for 1 hour, turning occasionally.
Lay the beef on a clean cloth to absorb excess liquid.
Batter and fry
Dip the beef slices in a batter made from egg, milk, flour, and a little salt.
Fry in dripping or lard until golden brown.
Drain off excess grease and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Its acidity flavours the beef and tenderises its surface during marinating.
- Egg
- Binds the batter and helps it set into a coating around the beef.
- Prepared flour
- Forms the body of the batter, giving the coating structure once fried.
- Milk
- Adds moisture to the batter so it coats the beef smoothly.
- Made mustard
- Adds sharp, pungent flavour to the marinade.
The step that matters
Drying the beef before battering. Excess liquid left on the marinated slices dilutes the batter and creates steam, so the coating can slide off or fry unevenly. Patting the slices dry on a cloth helps the batter adhere and brown.
