Why it works: Wine and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,157 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Calves' Foot Broth
Ingredients
Directions
Prepare the broth
Soak the calves' feet in cold water for 30 minutes.
Boil the feet in 2 quarts of water until reduced to less than 1 quart.
Strain the broth and let it cool until it forms a jelly.
Finish the jelly
Take the desired amount of jelly, add a little wine and white sugar, and heat gently while stirring continuously.
Once dissolved, add a small bit of butter and flavor with lemon or orange peel, or a blade of mace.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' feet
- Release gelatin as they simmer, which lets the broth set into a jelly when cooled.
- Water
- Extracts collagen and flavour from the feet during the long boil, forming the broth.
- White sugar
- Adds sweetness to balance the savoury broth and the wine.
- Wine
- Adds acidity and aroma to the jelly.
- Butter
- Adds richness and a silkier mouthfeel to the finished jelly.
The step that matters
Reducing the broth and heating the jelly gently. Boiling until under 1 quart concentrates the gelatin so the broth sets firmly on cooling. When reheating the jelly, keep the heat gentle and stir constantly, because strong heat can scorch the sugar and wine and gelatin can break down, leaving the jelly weak or grainy.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, wine, butter):
- Vanillafits better
- Applefits better
- Grapefits about as well
- Lemonthe original
Fit is the average pairing score against sugar, wine, butter. Candidates are from the same food group and used in at least 100 recipes.
