Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrow
- Forms the main body of the topping, providing soft flesh and moisture once cooked.
- Butter
- Adds richness and flavor, and browns when the slices are fried.
- Vinegar
- Adds acidity that brightens the buttery, mild flavor of the marrow.
The step that matters
Boil the marrow until tender before slicing. Raw marrow is too firm to slice cleanly. Cooking softens its flesh so the slices hold their shape on the toast without tearing.
