Why it works: Milk and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that gives the rolls their structure and chew.
- Mashed potato
- Adds moisture and softness, helping the rolls stay tender after baking.
- Shortening
- Adds fat that tenderizes the crumb and makes the dough easier to roll.
- Yeast
- Produces gas during rising, which leavens the dough and makes it airy.
- Egg
- Adds structure and richness to the dough.
- Sugar
- Feeds the yeast and adds mild sweetness and browning.
