Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Spare Rib
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
If the spare rib is not already salted, sprinkle it with coarse sea salt.
Roast
Roast the spare rib for 2.5 to 3 hours, basting with butter and dredging with flour periodically.
About 20 minutes before it is done, sift a little powdered sage over the rib.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Spare rib
- The main cut; its meat cooks slowly to become tender over the long roast.
- Butter
- Basting adds fat and moisture to the surface and helps it brown.
- Flour
- Dredging builds a light coating that helps the surface brown and crisp.
- Powdered sage
- Adds aromatic, herbal flavour to the outside of the rib near the end.
The step that matters
Basting and dredging through the roast. Basting with butter and dredging with flour at intervals keeps the surface moist and helps it brown evenly over a long roast. Skipping these can leave the outside dry and pale.
Swap the sage
How well each one fits the dish's main ingredients (butter, flour):
- Jalapenofits better
- Capersfits better
- Nutmegfits better
- Sagethe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
