Why it works: Milk and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Gelling agent that sets the liquid into a firm jelly as it cools.
- Milk
- Adds richness and a creamy, opaque body to the jelly.
- White sugar
- Adds sweetness and balances the flavour of the jelly.
The step that matters
Boiling down the isinglass to 1 pint. Boiling dissolves the isinglass and reduces the water, concentrating it. The amount of isinglass left in the liquid determines how firmly the jelly sets, so the reduction should reach the stated volume before straining and adding the milk.
