Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Main protein; long boiling softens connective tissue so it becomes tender.
- Potatoes
- Starch that softens and thickens the mixture as it cooks.
- Onions
- Add sweetness and aroma as they soften in the cooking liquid.
- Butter
- Fat that adds richness and a smoother mouthfeel.
The step that matters
Boil the meat for 3 hours.. A long, gentle boil is needed to break down the meat's connective tissue. If the liquid boils down too far or the meat is rushed, it stays tough and the mixture can scorch.
