Why it works: Milk and egg are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Prepare the filling
Scrape the inside out of the penny roll.
Soak the roll in milk if filling with sweets, or in gravy if filling with savory ingredients.
For sweet filling, sprinkle with sugar; for savory filling, sprinkle with coarse sea salt.
Add a few grated crumbs and eggs to the filling.
Bake
Bake until golden.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Penny roll
- Forms the edible shell that holds the filling while it bakes.
- Eggs
- Bind the filling and help it set as it cooks.
- Grated crumbs
- Absorb moisture and add body to the filling.
The step that matters
Soaking the roll. The roll must soak enough to become soft and absorbent, but not so long that it falls apart. Soft bread takes in the liquid and holds the filling, while overly saturated bread collapses and bakes unevenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
