Why it works: Rhubarb and chocolate work together. They rank in the top 15% of all ingredient pairs, and 29 recipes mention both. Both carry acetic acid, which smells sour, vinegar. The science ↓
The recipe
1 loaf (9×5)Ingredients
Contains: egg, milk, wheat (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.
Preheat the oven to 350°F (177°C). Grease a 9×5-inch loaf pan with a little of the softened butter.
Toss the chopped rhubarb with about half the sugar in a bowl and let it sit 10 minutes. Drain off any liquid before using.
Whisk the flour, baking powder, baking soda, nutmeg and salt together in a medium bowl.
Beat the remaining butter with the remaining sugar until light and fluffy, about 3 minutes. Beat in the eggs one at a time, then the vanilla, sour cream and mashed bananas.
Fold the dry ingredients into the wet mixture just until no streaks of flour remain. Do not overmix.
Fold in the drained rhubarb and the chocolate chips. Spread the batter evenly into the prepared pan.
Bake 60 to 70 minutes, until a toothpick inserted in the center comes out clean and the top is golden brown.
Cool the loaf in the pan for 10 minutes, then turn it out onto a rack and cool completely before slicing.

Fit is the average pairing score against rhubarb, sugar, flour, butter, egg, banana, cream. 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).
