Why it works: Potato and peanut match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 161 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Grandma's Potato Candy
Ingredients
Directions
Make the dough
Add vanilla and salt to mashed potatoes. Chill.
Add confectioners' sugar slowly to chilled potatoes until mixture is stiff and dry.
Divide mixture into 3 parts.
Roll and fill
Working with one part at a time, roll out to about a 1/4 inch thickness on waxed paper (it should form a rectangle about 4x12 inch).
Spread with a thin layer of peanut butter.
Roll up as for jelly roll.
Repeat with remaining potato mixture and peanut butter.
Chill and serve
Chill several hours.
Slice (not too thick; this is rich).
Store in refrigerator.

Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 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
- Mashed potatoes
- Provides moisture and body that the sugar stiffens into a pliable dough.
- Confectioners' sugar
- Sweetens and dries the potato mixture, firming it so it can be rolled.
- Smooth peanut butter
- Adds rich flavor and fat as the filling spread inside the rolls.
The step that matters
Adding the confectioners' sugar slowly. Sugar absorbs the potato's moisture gradually. Adding it all at once can make the mixture gluey or leave it crumbly, so it may not roll out cleanly without cracking.
Swap the potato
How well each one fits the dish's main ingredients (vanilla, sugar, peanut, butter):
- Sweet potatofits better
- Capsicumfits about as well
- Potatothe original
- Arrowrootfits about as well
Fit is the average pairing score against vanilla, sugar, peanut, butter. Candidates are from the same food group and used in at least 100 recipes.
