Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Black Currant Lozenges
Ingredients
Directions
Prepare the juice
Boil or bake the black currants in a jar until the juice separates.
Press the juice from the fruit or measure the fruit into a preserving pan.
Boil the fruit or juice for about 30 minutes before adding sugar.
Make the lozenges
Add ½ pound of sugar, 1 ounce of cream of tartar, and 1 ounce of gum arabic mixed with a small amount of boiling juice.
Boil the mixture until it is very stiff and candies on the sides of the pan.
Pour the mixture onto flat dishes or upside-down plates, keeping the thickness to ⅛ inch.
Dry the lozenges in the sun or near a fire, turning them carefully when one side hardens.
Once dry, cut them into lozenges using a sharp tin cutter.
Shake a little magnesia among the lozenges to prevent sticking.
Store
Store in writing paper or tin boxes in a very dry place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black currants
- Provide the flavour, colour and the pectin-rich juice that forms the base of the lozenges.
- Fine loaf sugar
- Adds sweetness and, once boiled stiff, helps the mixture set into a firm, chewy lozenge.
- Cream of tartar
- Adds acidity that keeps the sugar from crystallising, giving a smoother, less grainy texture.
- Gum arabic
- Acts as a binder and thickener that gives the lozenges body and helps them hold their shape.
The step that matters
Boiling the mixture to a very stiff stage. Boiling until the mixture is very stiff and candies on the pan sides concentrates the sugar so it sets firm when dried. Under-boiling leaves lozenges soft and sticky, while over-boiling makes them brittle.
