Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts and browns to add a nutty aroma and fat to the base.
- Sugar
- Caramelises as it darkens, adding colour and a deeper, slightly bitter sweetness.
- Flour
- Coats the caramelised mixture so it can thicken and colour gravy or soup.
The step that matters
Stirring the sugar until dark brown. Sugar caramelises quickly once it gets hot, and it can go from amber to burnt in seconds. Taking it off the heat at the right colour keeps the flavour rich instead of acrid.
