Why it works: Orange and brandy are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 2,706 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
To Make Orange Juice to Keep
Ingredients
Directions
Prepare the juice
Squeeze the oranges into a pan.
Strain the juice through a coarse sieve, then through a fine sieve.
Measure the juice; for every pint, add 1 pound of fine loaf sugar.
Cover and let it stand overnight.
Remove the scum and stir well.
Bottle and store
Pour into dry pint bottles, adding 1 tablespoon of brandy to each.
Seal the bottles with leather over the cork.
Store in a dry place; it will last for two years.

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
- Oranges
- Provide the juice, which supplies the main flavour and acidity of the preserve.
- Fine loaf sugar
- Sweetens the juice and helps preserve it by binding water and inhibiting microbial growth.
- Brandy
- Adds alcohol that further helps keep the juice from spoiling and adds aroma.
The step that matters
Remove the scum and stir well. Scum that forms while the juice stands contains impurities and microbes that can spoil the preserve if left in. Stirring redistributes the dissolved sugar so the juice keeps evenly.
Swap the orange
How well each one fits the dish's main ingredients (sugar, brandy):
- Vanillafits better
- Apricotfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, brandy. Candidates are from the same food group and used in at least 100 recipes.
