Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the junket once the rennet sets it into a soft custard.
- Rennet
- Enzyme that curdles the milk proteins so the mixture sets into a delicate, spoonable gel.
- Chocolate
- Provides the main flavour and colour, and thickens the base when melted with water.
- Strong coffee
- Supplies the main flavour and aroma for the coffee version.
- Sugar
- Adds sweetness to balance the coffee or chocolate flavour.
The step that matters
Add the rennet when the milk is only lukewarm. Rennet works best at about body temperature. If the milk is too hot the enzyme is destroyed and the junket will not set; if it is cold the setting is slow and weak.
