The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: guaiacol (smoky, sweet).

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

Invalid food
Forms the base of the jelly and supplies most of its body and substance.
Milk
Adds moisture and softness, thinning the base into a smooth mixture.
French leaf gelatine
Sets the liquid into a firm jelly as it cools.
Castor sugar
Adds sweetness and balances the flavour of the jelly.

The step that matters

Dissolving the gelatine while hot. Gelatine must be fully dissolved in hot liquid, not boiling, so it sets evenly. Undissolved granules leave a grainy, weak jelly.
