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 ↓
Modern Cookery
Ingredients
Directions
Roast
Spit the joint and place it far from the fire initially.
Baste constantly.
When two-thirds done, move it closer to the fire to brown.
A few minutes before removing, sprinkle with salt.
Baste with dripping or butter.
Flour and finish
Dredge with flour.
To avoid raw flour taste, dredge the roast with flour early for a savory crust.
If wrapped in buttered paper, do not flour until 15-20 minutes before serving.
Keep the dripping pan clean and draw it back when stirring the fire.

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
- Meat or poultry
- The main protein, which browns and develops savory flavor as its surface heats.
- Butter or its own dripping
- Fat that bastes the surface, adding richness and helping it brown evenly.
- Flour
- Forms a dry coating that browns into a savory crust and helps seal in juices.
The step that matters
Dredging the roast with flour early. Flour applied early is cooked in the hot fat, which removes its raw, starchy taste and lets the coating brown into a crisp, savory crust. Flour added late stays pasty and raw-tasting.
