Why it works: Flour and butter 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 ↓
Bakbecued Pork
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Place the loin of pork in the oven without water.
Sprinkle with flour, pepper, and coarse sea salt.
Baste with butter.
Cook and serve
Cook for 2 to 3 hours, or until very brown.
Pour ½ cup walnut ketchup into the gravy.
Serve with fried apples.

Flour and butter 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
- Loin of pork
- Main meat; long cooking breaks down connective tissue, leaving it tender.
- Flour
- Sprinkled on the meat to help the surface brown and to thicken the gravy.
- Butter
- Fat that carries heat over the surface, adding richness and aiding browning.
- Walnut ketchup
- Adds acidity and savoury depth to the gravy.
The step that matters
Cooking until very brown. The pork is roasted without water for 2 to 3 hours, so it can dry out before it browns. Browning comes from Maillard reactions on the surface, which need dry heat and the sugars and amino acids in the meat and flour.
Swap the walnut
How well each one fits the dish's main ingredients (pork, flour, pepper, butter, ketchup):
- Beansfits about as well
- Walnutthe original
- Chestnutfits about as well
- Almondfits about as well
Fit is the average pairing score against pork, flour, pepper, butter, ketchup. Candidates are from the same food group and used in at least 100 recipes.
