Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
Gelatin-like setting agent that firms the liquid into a sponge that holds its shape.
Orange juice
Provides the main flavour and liquid base for the sponge.
Sugar
Adds sweetness to balance the citrus acidity.
Lemon juice
Adds acidity that sharpens the orange flavour.

The step that matters

Whisk until it resembles a sponge. Whisking while the mixture is cooling and starting to thicken traps air bubbles that stay in place as it sets. Whisking too early or too late gives a dense or uneven texture.
