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 ↓

What each ingredient does
- Pig's head
- Supplies the meat, and skin and bones that release gelatin to help the dish set.
- Saltpetre
- Cures the meat, helping preserve it and giving it a pink colour.
- Common salt
- Draws out moisture and seasons the meat during curing.
The step that matters
Let it cool to set. Gelatin released from the skin and bones during boiling firms as the dish cools, binding the chopped meat. Pressing firmly before it cools helps the pieces knit together into a firm, sliceable collar.
