Why it works: Lemon and clove match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 8,150 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Frying until golden builds sweetness and savory browned flavor into the gravy.
- Flour
- Thickens the liquid as it cooks, giving the gravy body.
- Butter
- Carries the onion's flavor and adds richness to the gravy.
- Beer
- Adds malty, slightly bitter depth to the liquid base.
- Catsup
- Adds sweetness and acidity that rounds out the gravy's savory flavor.
The step that matters
Frying the onion until golden. Onion that is pale or burnt will taste flat or bitter. Slow, even browning develops sweet, savory flavor that carries through the whole gravy.
