Why it works: Grape and sugar are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 7,490 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Grape Marmalade
Ingredients
Directions
The book gives no oven temperature. The 222°F (106°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the grapes
Wash and stem the grapes.
Separate the pulp from the skins.
Make the pulp and skins
Cook the pulp for 10 minutes.
Press the cooked pulp through a sieve to remove seeds.
Add ½ cup water to each quart of skins.
Boil the skins with water until tender.
Combine the pulp and skins.
Measure the mixture.
Cook and jar
For every quart of the mixture, add 1 pound of sugar.
Bring the mixture to a boil.
Add the sugar to the boiling mixture.
Cook, stirring frequently, until the mixture reaches 222°F (106°C).
Pour the hot mixture into sterilized jars.
Process the jars as you would for jam and preserves.

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 pulp and skins, whose natural pectin helps the marmalade set.
- Sugar
- Adds sweetness and body, and helps the mixture thicken and preserve as it cooks.
- Water
- Helps soften the skins so they become tender before combining.
The step that matters
Cooking to 222°F (106°C). Sugar concentration and boiling point rise together as water evaporates. Stopping at the right temperature gives a thick set; undercooking leaves it runny, while overcooking can make it stiff and sugary.
