Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar: Provides sweetness and the body of the syrup base.
Tartaric acid: Adds sharp acidity that balances the sweetness and gives the drink its tartness.
Lemon essence: Supplies the bright lemon aroma and flavour.
Ginger essence: Adds a warm, spicy aroma and flavour.

The step that matters

Adding the soda. Soda reacts with the tartaric acid to release carbon dioxide, which gives the fizz. Added too early, or to a drink left standing, the gas escapes and the nectar goes flat. Add it just before serving.

Swap the ginger

How well each one fits the dish's main ingredients (sugar, lemon, egg):
