Why it works: Guava and rum share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and 11 recipes mention both. Both carry ethyl pentanoate, which smells yeast, fruit. The science ↓
The recipe
3 cupsIngredients
Contains: soy, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Combine the cold water and guava paste in a saucepan over medium-low heat, stirring until the guava paste fully dissolves, about 5 minutes.
Stir in the apple cider vinegar, dark rum, tomato paste, lemon juice, minced onion, minced ginger, soy sauce, ketchup, Worcestershire sauce, minced garlic, and minced scotch bonnet pepper.
Bring the mixture to a gentle simmer over medium heat, then reduce the heat to low and cook uncovered for about 10 minutes, stirring often, until thickened and glossy.
Season with kosher salt and pepper to taste.
Remove from the heat and let cool for a few minutes. Taste and adjust the scotch bonnet, salt, or pepper before using.
Optional: blend the sauce until smooth for a finer texture, then store it in a covered container in the refrigerator.

Fit is the average pairing score against guava, apple cider vinegar, rum, tomato, lemon, ginger, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
