Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the milk and bread together and set into a tender, custardy coating when cooked.
- Milk
- Adds moisture that soaks into the bread and keeps the centre soft.
- Stale bread
- Dry crumb soaks up the egg mixture without falling apart, giving structure and a soft interior.
- Butter
- Fat that helps the surface brown evenly and adds richness.
The step that matters
Dip the stale bread slices in the egg mixture.. Stale bread absorbs liquid well, but soaking too long makes slices soggy and fragile, so dip briefly until just saturated.
Swap the cinnamon
How well each one fits the dish's main ingredients (egg, milk, bread, butter):
- Nutmegfits about as well
- Cinnamonthe original
- Parsleyfits less well
- Capersfits less well
Fit is the average pairing score against egg, milk, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
