Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Loaf sugar
- Dissolves to sweeten the base and balance the sharp citrus and sherry.
- Lemon juice
- Adds acidity and bright lemon flavour.
- Sherry
- Adds body and aroma to the liqueur.
- Cold milk
- Softens the liquid, and its proteins are removed when the mixture is strained clear.
- Pearl barley
- Gives a light body and mild grain flavour to the barley drink.
The step that matters
Strain through a jelly bag until clear. Milk proteins curdle with the acid and must be filtered out; rushing this leaves the liqueur cloudy and gritty.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, sherry, milk, barley):
- Vanillafits better
- Figfits better
- Applefits better
- Lemonthe original
Fit is the average pairing score against sugar, sherry, milk, barley. Candidates are from the same food group and used in at least 100 recipes.
