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 ↓
Port Wine Sauce, for Game
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1-2 minutes until lightly browned.
Gradually add the port wine, stirring constantly until the sauce thickens.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Port wine
- Supplies the liquid and the sweet, rich flavour that forms the sauce.
- Butter
- Adds fat and richness and helps flour cook into a smooth base.
- Flour
- Thickens the sauce as its starch swells when heated in liquid.
The step that matters
Adding the port wine gradually. Flour starch clumps if liquid is poured in all at once. Adding the port slowly while stirring constantly disperses the starch evenly, so the sauce thickens smoothly without 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.
