Why it works: Sweet potato and flour work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweet Potato Pone
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the grated sweet potatoes with molasses, baking soda, salt, melted bacon grease or butter, flour, and ground spice.
Pour the mixture into a greased baking pan.
Bake and serve
Bake slowly until well done and browned, about 45-60 minutes.
Serve hot or cold, with gravy and meat or with milk and sugar.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the starchy bulk that gives the cake its dense, moist body.
- Molasses
- Adds sweetness and dark colour, and helps the cake brown during baking.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and lighten.
- Melted bacon grease or butter
- Adds fat for moisture and a rich, tender texture.
- Flour
- Adds a small amount of structure to help hold the cake together.
The step that matters
Bake slowly until well done and browned. Sweet potato and molasses are dense and high in sugar, so the centre sets slowly and the surface browns quickly. Checking that the middle is fully cooked before removing the cake prevents a gummy, underbaked interior.
