Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beetroots
- Give the stew its main body, colour and earthy sweetness.
- Onions
- Add savoury flavour and body when softened in butter.
- Butter
- Adds richness and carries flavour when the onions are sautéed.
- Flour
- Thickens the milk into a smooth, body-giving base.
- Milk
- Forms the creamy liquid that becomes the thickened base.
- Vinegar
- Adds acidity that brightens the sweet flavour of the beetroot.
The step that matters
Simmer slowly for one hour. Keeping the heat low prevents the milk-based mixture from scorching or curdling at the bottom of the pan. A gentle simmer lets the flavours blend while the beetroot softens evenly.
