The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Grapes
- Provide the fruit base, flavour, and natural pectin from the skins and pulp.
- Sugar
- Adds sweetness and, as it concentrates in boiling, helps the preserve thicken and set.
- Paraffin
- Forms a sealing layer on the surface that keeps air out of the preserve.
The step that matters
Boil steadily for 30 minutes. A steady boil evaporates water and concentrates the sugar and fruit pectin so the preserve sets. Too short a boil leaves it runny, while a longer boil can darken the flavour and make it stiff.
