Why it works: Sweet potato and butter match in chemistry and in kitchens. They rank in the top 12% of all ingredient pairs, and 1,489 recipes mention both. Both carry 2,3-pentanedione, which smells butter, sweet. The science ↓
The recipe
Serves 6Ingredients
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.
Put the sweet potato puree, egg and salt in a large bowl and mix until smooth.
Add the rice flour and arrowroot powder a little at a time, mixing until a soft, slightly tacky dough forms. Add more rice flour only if the dough is too sticky to handle.
Dust a work surface with rice flour. Divide the dough into 4 pieces, roll each into a rope about 3/4 inch (2 cm) thick, and cut into 1-inch (2.5 cm) pieces.
Bring a large pot of water to a boil. Add the gnocchi in batches and cook until they float, about 2 to 3 minutes. Lift out with a slotted spoon and drain.
Melt the butter in a large skillet over medium heat, swirling often, until it foams and turns golden brown with a nutty smell, about 3 to 4 minutes.
Add the drained gnocchi to the brown butter and cook for 1 to 2 minutes, turning gently, until lightly golden in spots.
Transfer the gnocchi to plates and top with the shaved Parmesan. Serve right away.

Fit is the average pairing score against sweet potato, yam, egg, rice, arrowroot, butter. 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).
