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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mutton
Hang the leg of mutton in a cool place for 2 weeks, washing it with vinegar every other day.
Rub the mutton with lemon juice.
Rub the mutton with a cut onion.
Rub the mutton with salad oil.
Roast
Place the mutton in a covered roaster with boiling water.
Cook the mutton in a hot oven at 400°F (200°C) for 30 minutes.
Transfer the mutton to a cooler oven at 350°F (175°C).
Cook the mutton for 15 minutes per pound.
Half an hour before finishing, baste the mutton with gravy mixed with melted currant jelly.
Baste the mutton again with butter.
Sprinkle the mutton with pepper, salt, and flour.
Brown the mutton on the upper rack of the oven.
Make the gravy and serve
Pour off the gravy.
Cool the gravy to skim off the fat.
Strain the gravy.
Return the gravy to heat, thickening it with browned flour.
Add sherry to the gravy.
Pour half of the gravy over the meat.
Serve the remaining gravy separately.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Mutton
- Long hanging and washing with vinegar tenderise and flavour the lean meat before roasting.
- Currant jelly
- Adds sweetness and a glossy glaze to the gravy used for basting.
- Butter
- Adds fat and richness, helping the outer surface brown during basting.
- Flour
- Thickens the gravy and helps the coating brown in the oven.
- Sherry
- Adds acidity and aroma to the finished gravy.
The step that matters
Cool the gravy to skim off the fat. Fat separates and rises as gravy cools, so skimming it first leaves a lighter sauce. Skipping this step makes the gravy greasy before the flour thickens it.
Swap the currant
How well each one fits the dish's main ingredients (mutton, vinegar, lemon, onion, butter, pepper, flour):
- Limefits better
- Mangofits better
- Cherryfits better
- Currantthe original
Fit is the average pairing score against mutton, vinegar, lemon, onion, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
