Beef and flour barely smell alike, yet cooks put them together in 10,677 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides meat and bones that give the stock its body and savory flavor.
- Leftover roast beef or veal gravy
- Adds concentrated meaty flavor and color to the finished soup.
- Chopped onions
- Browning in fat builds sweetness and savory depth in the base.
- Flour
- Browned with onions and fat, it thickens the soup and adds roasted flavor.
- Fat
- Carries flavor from the onions and gravy and helps brown the flour.
The step that matters
Brown chopped onions and flour in the hot gravy. Flour that is not cooked long enough tastes raw and pasty. Browning it in fat toasts the starch and builds roasted flavor before the liquid is added.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour):
- Chivefits better
- Arrowrootfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against beef, flour. Candidates are from the same food group and used in at least 100 recipes.
