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 ↓
Fresh Pork Pot-pie
Ingredients
Directions
Prepare the filling
Boil the spare rib until tender, skimming off any scum.
Season the broth with salt and pepper.
Thicken the gravy with a little flour half an hour before serving.
Remove the bones and most of the gravy, leaving enough to cover the pot half an inch above the rim.
Make the crust and cook
Prepare the crust by mixing a small amount of butter into flour to form a light dough.
Roll out the dough thinly.
Cut the dough into small squares.
Let the squares rest until light.
Place the crust in the pot.
Cover tightly.
Boil steadily for 45 minutes.

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
- Spare rib
- Provides the meat and rich flavour that the broth and gravy are built on.
- Flour
- Thickens the gravy and forms the light dough for the crust.
- Butter
- Adds fat and richness to the crust dough, tenderising it.
The step that matters
Thicken the gravy with a little flour half an hour before serving. Flour thickens liquid only when it is heated and given time to cook, so adding it too late leaves the gravy thin and starchy-tasting. Stirring it in well avoids lumps.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
