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 Short Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Boil and mash the sweet potatoes.
In a bowl, combine the mashed sweet potatoes with lard and flour, mixing smoothly without overworking.
Roll out the dough and cut into desired shapes.
Bake
Bake in a preheated oven at 400°F (200°C) until golden brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Sweet potatoes
- Add moisture, natural sweetness and a soft crumb to the dough.
- All-purpose flour
- Provides the structure that holds the shortcake together as it bakes.
- Lard
- Adds fat that shortens gluten strands, giving a tender, crumbly texture.
- Eggs
- Bind the dough and add richness and structure.
The step that matters
Mixing the dough without overworking it. Working flour-based dough too much develops gluten, which makes shortcake tough and dense instead of tender and crumbly.
