Shared aroma: (e,e)-2,4-decadienal (fatty, deep fried).
Egg and lemon barely smell alike, yet cooks put them together in 44,316 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
- Gelatine
- Sets the liquid into a light, wobbly structure as it cools.
- Egg whites
- Whipped into the mixture to add air and a light, foamy texture.
- Lemon juice
- Adds sharp acidity that brightens the flavour of the sponge.
The step that matters
Add the beaten egg whites after the mixture cools slightly. If the liquid is still too hot, it can cook the egg whites and deflate the foam. Letting it cool a little first helps the whites keep their air while the gelatine begins to thicken.
