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 ↓
Vegetable Marrow or Gourd
Ingredients
Directions
Prepare
Gather the vegetable marrow when it is the size of an egg.
Boil it in salted water for 30 minutes or until tender.
Cut it into ½ inch thick slices.
Assemble and serve
Lay the slices over buttered toast.
Sprinkle with pepper and coarse sea salt.
Pour melted butter over the top.
Alternative method
If the marrow is large, scoop out the seedy part before cooking.
Alternatively, cut the raw slices, scoop out the seeds, fry in butter, and serve with melted butter and vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrow or gourd
- Its flesh softens when boiled, giving the toast a tender, mild topping.
- Butter
- Adds richness and flavor, and browns when fried in the alternative method.
- Vinegar
- Adds sharp acidity that cuts through the richness of the butter.
The step that matters
Boiling until tender. Boiling softens the marrow's fibers and cell walls. Stopping too early leaves it firm and fibrous, while boiling too long makes it watery and mushy on the toast.
