Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beetroot
- Forms the main body of the stew and provides colour, earthiness and sweetness as it cooks.
- Onions
- Soften and sweeten as they cook gently, adding savoury depth to the sauce.
- Flour
- Cooked with the butter and onions, it thickens the milk into a smooth sauce.
- Milk
- Forms the liquid base of the sauce, giving it body and a creamy texture.
- Butter
- Adds fat and richness, and carries the onion flavour into the sauce.
- Vinegar
- Adds acidity that brightens the sweet beetroot and balances the rich sauce.
The step that matters
Pour milk and stir until it boils. Flour must be stirred into the fat and then the milk while it heats, or lumps form. Bringing it to a boil and stirring keeps the sauce smooth and fully thickened.
