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

What each ingredient does

Egg
Adds richness and a smooth, thick body to the drink.
Malt vinegar
Provides sharp acidity that cuts through the richness of the egg.
Iced soda water
Adds fizz and a lighter, livelier texture.

The step that matters

Break the egg into the glass without breaking the yolk. The yolk is held together by its membrane. If it breaks, the yolk mixes into the vinegar and soda water, changing the drink's texture and making it cloudier and thicker than intended.
