Why it works: Sugar and spread match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 260 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Sugar Vinegar
Ingredients
Directions
Prepare the sugar water
Boil the spring water and skim thoroughly.
Add 2 pounds of coarse sugar to every gallon of boiling water.
When cool, mix in 1 quart of cold water for every gallon of hot water.
Ferment
Add a toast spread with yeast to the mixture.
Stir for nine days, then transfer to a barrel.
Place the barrel in a sunny spot and cover the bung-hole with a piece of slate.

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
- Coarse sugar
- Provides the sugar that yeast ferments into the acids that make the vinegar.
- Spring water
- Forms the liquid base in which the sugar dissolves and the fermentation takes place.
- Yeast
- Converts the sugar into alcohol and starts the fermentation that later turns into acetic acid.
The step that matters
Adding the yeast-spread toast at the right temperature. The mixture should be cool when the yeast is added, because hot liquid can kill yeast cells. Cooling the sugar water first keeps the yeast alive so it can start fermenting the sugar.
