Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients

Directions

Prepare the grapes

  1. Take the grapes when nearly ripe and cut the stalks about ½ inch from the fruit.

  2. Soak the grapes in cold water with the alum until they simmer over low heat, then remove them from the heat.

  3. Place the grapes in cold water, then drain them.

  4. Pack the grapes closely into a preserving pan.

Make the syrup

  1. Pour enough clarified sugar over the grapes to cover them, then simmer them for 2–3 minutes.

  2. Set the grapes aside in an earthen pan until the next day.

  3. Drain the grapes.

Repeat over two days

  1. Boil the syrup with more sugar until thick, add the grapes back, and simmer for 3 more minutes, repeating this for two days.

  2. On the final day, boil clarified sugar until it reaches a blow stage.

Jar and cover

  1. Place the grapes into jars and pour the syrup over them.

  2. Once cooled, cover with a bladder.

  3. Cover with leather.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green gages
The fruit itself; soaking with alum firms its flesh so it holds its shape in the syrup.
Alum
Firms the fruit's tissue so it keeps its shape through repeated simmering.
Clarified sugar
Sweetens the fruit and draws out water, preserving it in a thick syrup.
Additional sugar
Thickens the syrup as it is boiled down, helping it cling to the fruit.

The step that matters

Simmering and resting over two days. Brief simmering followed by standing lets sugar slowly replace the water in the fruit. Boiling hard or rushing the process can split the skins and leave the fruit shriveled or tough.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, syrup):

  1. Chestnutfits better
  2. Almondfits better
  3. Hazelnutfits better
  4. Walnutthe original

Fit is the average pairing score against sugar, syrup. Candidates are from the same food group and used in at least 100 recipes.
