Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Any kind of meat
- Provides the main substance; slow stewing turns its connective tissue tender.
- Meat fryings or butter
- Fat that browns the surface of the meat and adds rich flavour.
- Irish or sweet potatoes or turnips
- Absorb cooking juices and brown alongside the meat for added sweetness.
The step that matters
Browning the roast in the pot. Searing the meat until browned before adding water builds deep flavour through the Maillard reaction. Pale meat will taste flat after stewing.
