Why it works: Sage and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 887 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Roast Spare Rib
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Roast
Preheat the oven to 400°F (200°C).
Baste the spare rib with butter every few minutes.
Baste the spare rib with its own gravy every few minutes.
Sprinkle the rib with bread crumbs, sage, pepper, sea salt, and minced onion before removing from the oven.
Cook for an additional 5 minutes, basting once more with butter.
Make the gravy and serve
Skim the gravy, add hot water, thicken with brown flour, and squeeze in lemon juice.
Strain the gravy and pour it over the meat.
Serve with tomato ketchup on the side or mixed into the gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds moisture and richness, and helps the rib brown as it bastes.
- Fine bread crumbs
- Form a crisp, savoury crust on the surface of the rib.
- Brown flour
- Starch thickens the gravy so it coats the meat.
- Lemon juice
- Adds acidity that brightens the rich gravy.
- Onion
- Adds savoury aroma and mild sweetness as it cooks.
The step that matters
Thickening the gravy with brown flour. Flour clumps if it is not whisked evenly into the hot liquid. Its starch swells with heat, so the gravy thickens smoothly only when the flour is fully mixed in.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (butter, bread, sage, pepper, onion, flour, lemon):
- Shallotfits better
- Leekfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against butter, bread, sage, pepper, onion, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
