Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grits
- Thickens the milk as it cooks, giving the soup a creamy body.
- New milk
- Cooks with the grits to form the creamy base and adds richness.
- Leek
- Adds mild onion-like aroma and flavour to the soup.
The step that matters
Boil the grits in new milk until thick like cream. Grits thicken as their starch swells and gelatinises in hot liquid. Stopping too early leaves the soup thin, while overcooking and scorching the milk can make it stick and taste burnt. Stir often to keep the texture smooth.
