Why it works: Wheat and sweet potato share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and cooks put them together in 59 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Potato Muffins
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potato
Boil the potatoes in their skins until tender, then drain, peel, and mash them finely.
Make the batter
Sift together the flour, salt, and baking powder.
Beat the eggs until light and mix them with the cooled mashed potato.
Add the melted shortening, then alternate adding the flour mixture and liquid until a stiff batter forms.
Bake
Drop spoonfuls of the batter into greased muffin pans until half full.
Bake in a moderate oven at 350°F (175°C) for about 30 minutes.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Wheat flour
- Provides the structure that holds the muffins together as they set.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Sweet potato
- Adds moisture and body to the batter, keeping the muffins tender.
- Shortening
- Adds fat for a tender crumb and softer texture.
- Baking powder
- Releases gas in the batter to help the muffins rise.
The step that matters
Adding the liquid to a stiff batter. Flour needs enough liquid to hydrate, but too much makes the batter loose and dense. Alternating flour and liquid helps the batter combine evenly without overworking the gluten, which keeps the muffins tender.
Swap the sweet potato

Fit is the average pairing score against wheat, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
