Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Eggs in Cases
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Place a piece of butter the size of a small nut and some chopped herbs in each case.
Melt the butter in the oven.
Assemble
Break a fresh egg into each case.
Season with coarse sea salt and cover with lightly browned bread crumbs.
Grate a little Parmesan cheese over the top.
Cook and serve
Steam slowly until cooked.
Optionally, pass a salamander over them before serving.
Serve in the cases.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm but tender custard-like texture when gently heated.
- Butter
- Adds fat for richness and flavour and helps keep the eggs moist.
- Bread crumbs
- Form a crisp, golden topping and add texture over the soft egg.
- Parmesan cheese
- Adds savoury flavour and helps the top brown when heated.
- Fresh herbs
- Add aroma and fresh flavour to the butter and egg.
The step that matters
Steam slowly until cooked. Egg proteins set at moderate heat. Too much heat or time makes the whites rubbery and dries the yolk, so keep the cooking gentle and check for a barely set centre.
“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.
