Why it works: Grape and brandy work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 711 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Grape Isinglass Jelly
Ingredients
Directions
Prepare the juice
Dissolve the isinglass or gelatine in the water.
Put the grapes in a saucepan and bruise them with a wooden spoon until the juice flows.
Strain the juice through two or three layers of muslin without pressure until clear.
Make and set the jelly
Boil the clear juice with the sugar and dissolved isinglass for 10 minutes.
Add the brandy and pour the mixture into an oiled mould.
Place the mould in a cool place until the jelly is firmly set.

Sugar and brandy barely smell alike, yet cooks put them together in 11,939 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass or gelatine
- Sets the juice into a firm, sliceable jelly as it cools.
- Purple grapes
- Provide the juice, flavour and colour that form the base of the jelly.
- Loaf sugar
- Adds sweetness and balances the tartness of the grape juice.
- Brandy
- Adds aroma and warmth to the finished jelly.
The step that matters
Straining without pressure. Pressing the grapes forces cloudy pulp and solids through the muslin, which leaves the jelly cloudy and can make it set unevenly. Letting the juice drip alone keeps it clear.
Swap the grape
How well each one fits the dish's main ingredients (sugar, brandy):
- Vanillafits better
- Apricotfits better
- Raisinfits better
- Grapethe original
Fit is the average pairing score against sugar, brandy. Candidates are from the same food group and used in at least 100 recipes.
