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 your oven to 350°F (175°C).
Roast
Roast the spare rib for 2.5 hours, or 3 hours if it is very large.
Baste the rib with butter while roasting.
Dredge the rib with flour.
Pound some gage and sprinkle it on the rib about 20 minutes before it is done.
Add a pinch of coarse sea salt if desired.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Is the main cut of meat that the whole dish is built around.
- Butter
- Adds fat and richness, helping the surface brown and stay moist while roasting.
- Flour
- Coats the rib, helping the outside brown and form a light crust.
- Gage (plum)
- Adds sweet-tart fruit flavour to the rib's surface during the final stretch of roasting.
The step that matters
Pound the gage and add it near the end. Adding the plum about 20 minutes before the rib is done keeps its fresh, tart flavour from cooking away, while the sugars in the fruit can darken quickly if left too long in the oven.
Swap the plum
How well each one fits the dish's main ingredients (butter, flour):
- Raisinfits better
- Vanillafits better
- Coconutfits better
- Plumthe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
