Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, and carries flavor into the sauce.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Sugar
- Adds sweetness and helps balance the tartness of the guava.
- Guava juice
- Supplies the liquid and the fruity flavor that the flour thickens.
The step that matters
Add the flour and mix thoroughly. The flour must be fully blended into the melted butter before liquid goes in. Dry flour left clumped will form lumps that do not dissolve, and the starch thickens unevenly.
Swap the guava
How well each one fits the dish's main ingredients (butter, flour, sugar):
- Raisinfits better
- Vanillafits better
- Figfits better
- Guavathe original
Fit is the average pairing score against butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
