Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion, carrot, turnip, and parsnip
- Browned vegetables build the soup's deep flavour and colour as they fry.
- Stock
- Forms the liquid base that extracts flavour from the vegetables and aromatics during simmering.
- Caramel (in the method)
- Adds a deeper amber colour and a slight toasted sweetness to the soup.
The step that matters
Fry the vegetables until delicate brown. Browning the vegetables produces Maillard reaction flavours that give the soup its depth. Pale or burnt vegetables change the flavour and colour noticeably, so stop at a light, even brown.
