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
- Red peppers
- Supply the main pepper flavour and colour, which the hot vinegar draws out.
- Strong vinegar
- Acidic liquid that extracts flavour from the peppers and helps preserve the finished liquid.
The step that matters
Reduce to 1 quart. Boiling evaporates water and concentrates both the vinegar's sharpness and the peppers' flavour. Stopping at the stated volume sets the strength of the final liquid, so the reduction needs to be measured rather than judged by eye.
