Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flank beef
- Provides the main meat, which becomes tender through long, gentle simmering.
- Onions
- Sweeten as they cook slowly and form the soft body of the dish.
- Flour
- Thickens the cooking liquid into a smooth gravy when mixed with cold water first.
The step that matters
Thickening the gravy with flour and cold water. Flour added directly to hot liquid clumps, because its starch granules swell on contact and stick together. Mixing it first with cold water separates the granules so they disperse evenly and thicken the gravy smoothly.
