Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pot Roast
Ingredients
Directions
Prepare and sear
Wipe the roast with a damp cloth and trim off some suet.
In a pot, sear the roast on all sides in the suet.
Season with salt and pepper to taste.
Cook the roast
Cook over a very low gas flame with the lid on until tender; do not add water.
Pour the can of tomatoes over the roast and cook for 15 minutes.
Make the gravy
Remove the roast from the pot and add enough flour to thicken the gravy.
Brown the flour, then add cold water to make sufficient gravy.
Season the gravy to taste with salt and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast
- Forms the main body of the dish, becoming tender through slow cooking.
- Suet
- Provides fat for searing, building browned flavor on the surface of the roast.
- Tomatoes
- Add acidity and flavor to the cooking liquid during the final braise.
- Flour
- Thickens the gravy as its starch swells in the cooking liquid.
The step that matters
Cook over a very low gas flame with the lid on; do not add water. Low, covered heat lets the tough connective tissue in the roast break down slowly into tender meat. Higher heat can scorch the bottom before the inside softens, and the roast's own juices create the moisture needed.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, flour):
- Arrowrootfits better
- Okrafits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
