Why it works: Cream and sugar 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 ↓
Coffee Cream, Much Admired
Ingredients
Directions
Prepare
Boil the calf's foot in water until it reduces to 1 pint of jelly, clear of sediment and fat.
Make 1 cup of very strong coffee and clarify it with 1 teaspoon of isinglass until bright.
Make the jelly
Combine the jelly with the coffee and add 1 pint of heavy cream and fine sugar to taste.
Bring the mixture to a boil.
Pour the mixture into a dish; it should set as a jelly but not be too stiff.

What each ingredient does
- Calf's foot
- Provides gelatin, which gives the jelly its body and ability to set.
- Isinglass
- Clarifies the coffee, making it bright and clear, and adds further setting power.
- Heavy cream
- Adds fat and richness, giving the set jelly a smooth, creamy texture.
- Strong coffee
- Provides the main flavour and aroma of the dish.
The step that matters
Pour the mixture into a dish; it should set as a jelly but not be too stiff.. Gelatin sets as it cools, and its strength depends on concentration and amount used. Too much gelatin makes a rubbery, stiff set, while too little fails to firm up, so the proportions and the cooling must be right.
