Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the stew and becomes tender during the long simmer.
- Cream
- Adds richness and a smooth, mellow mouthfeel to the liquid.
- Flour
- Thickens the liquid as its starch swells when heated.
- Butter
- Adds fat and richness, and combines with the flour to help thicken the stew.
- Hard-boiled eggs
- Add body and a soft, rich texture as they are chopped into the stew.
The step that matters
Add the flour and butter, then boil for 5 minutes. Flour thickens only when its starch is heated in liquid. Boiling for the full 5 minutes lets the starch swell and gives an even texture, while adding it without mixing first can leave lumps.
