Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered loaf sugar
- Provides the sweetness and dissolves into the syrup that sets into the drops.
- Water or strained lemon juice
- Dissolves the sugar so it can form a syrup that boils down to a firm, shapeable mass.
- Essence of peppermint
- Gives the drops their characteristic minty aroma and flavour.
The step that matters
Boiling the syrup for 10 minutes. Boiling drives off water and raises the sugar concentration, so the mixture sets firm when cooled. Too little boiling leaves drops that stay soft or sticky, while overboiling can make them brittle or caramelise.
Swap the peppermint
How well each one fits the dish's main ingredients (sugar, lemon, butter):
- Cinnamonfits better
- Parsleyfits better
- Nutmegfits better
- Peppermintthe original
Fit is the average pairing score against sugar, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
