Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Provides the sour, bright flavour that defines the drink.
- Cornstarch or arrowroot
- Thickens the liquid slightly, giving it a light, smooth body.
The step that matters
Thicken the hot lemonade. Cornstarch and arrowroot swell and thicken most reliably when the starch is heated in the liquid. Stir it into the hot lemonade so it dissolves evenly before the drink cools.
Swap the ginger
How well each one fits the dish's main ingredients (lemon, arrowroot):
- Capersfits better
- Turmericfits better
- Parsleyfits better
- Gingerthe original
