Why it works: Lemon and pepper 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 ↓
Scotch Collops
Ingredients
Directions
Prepare the veal
Cut the veal into slices ½ inch thick and trim into oval or round pieces, 2-3 inches in size.
Score the pieces on both sides with a sharp knife.
Sprinkle the pieces with salt, pepper, and mace or nutmeg.
Make the stock
In a stewpan, combine any bones and trimmings with the onion, lemon rind, a little mace or nutmeg, and a seasoning of salt and pepper.
Cover the mixture with cold water.
Simmer gently for about 1 hour.
Strain the liquid.
Add stock or water to make ½ pint.
Make the sauce
Melt the butter in a stewpan.
Add the flour.
Cook slowly until it turns nut‑brown.
Add the strained stock.
Stir until boiling.
Season to taste.
Simmer gently for about 20 minutes.
Add lemon juice to the sauce.
Cook and serve
Dip the collops in flour seasoned with salt and pepper.
Fry the collops lightly in hot butter or fat.
Drain the collops.
Arrange the collops on a hot dish.
Strain around the collops.
Garnish with bacon.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Cold roast veal
- Forms the main body of the dish, cooked gently in the sauce and fried briefly to brown.
- Butter
- Enriches the sauce and provides fat for frying the collops, adding richness and browning.
- Flour
- Cooked in butter to form a roux that thickens the sauce.
- Onion
- Adds savoury aromatic flavour to the stock made from bones and trimmings.
- Lemon juice
- Adds acidity that brightens the finished sauce.
The step that matters
Cook the flour until nut-brown. Cooking the butter and flour roux until nut-brown develops a toasted, nutty flavour and colour. Undercooked roux tastes raw and pale, while over-browned roux turns bitter.
Swap the mace
How well each one fits the dish's main ingredients (veal, butter, flour, lemon, onion, pepper):
- Parsleyfits better
- Thymefits better
- Sagefits better
- Macethe original
Fit is the average pairing score against veal, butter, flour, lemon, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
