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 ↓
Tripe with Oysters
Ingredients
Directions
Prepare the tripe
Clean, scrape, and wash the tripe thoroughly.
Boil the tripe in salted water until very tender.
Cut the cooked tripe into small pieces.
Make the sauce
In a stewpan, heat the boiling water.
Mix the butter with the flour, adding it half at a time.
Season with salt and pepper to taste.
Stir in the sugar and brown it until very dark.
Let it simmer for 5 to 10 minutes.
Finish and serve
Add the tripe and oysters, stir well, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the dish, becoming tender when boiled until soft.
- Butter
- Adds richness and fat, carrying flavor and giving the sauce a smooth body.
- Flour
- Thickens the butter and water mixture into a smooth, cohesive sauce.
- Sugar
- Browning it deeply adds caramel notes and a dark color to the sauce.
- Oysters
- Contribute briny, savory flavor and a tender texture to the finished dish.
The step that matters
Browning the sugar. Sugar darkens quickly once it starts to caramelize and can turn bitter if it burns. Stop at deep brown, before black, so the sauce tastes caramel rather than acrid.
