Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Grape Wine
Ingredients
Directions
Prepare the juice
Remove grapes from stems and pound them to a pulp.
Place the pulp in large stone jars and pour in half as much water as there are grapes.
Cover and let stand overnight.
Squeeze out and strain the juice.
Make the wine
Mix sugar and egg whites into the juice and boil for a few moments, skimming off any foam.
Let the mixture cool, then transfer it to a keg until fermentation is complete.
Bottle and store
Bottle the wine, adding a lump of sugar to each bottle.
Seal the corks and store in a cool place or bury in sawdust, turning occasionally.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White grapes
- Provide the juice and natural sugar that ferment into the wine.
- White sugar
- Feeds the yeast during fermentation and adds sweetness to the finished wine.
- Egg whites
- Bind and lift impurities and foam so they can be skimmed off during boiling.
The step that matters
Skimming off the foam while boiling. Egg whites and sugar are boiled into the juice, and foam rises as they coagulate and carry impurities to the surface. Removing it keeps the wine clearer and less cloudy.
Swap the grape
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Grapethe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
