Why it works: Egg and ham match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 4,516 recipes mention both. Both carry 2-octenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Cook the eggs
Place the eggs in boiling water and boil for 10 minutes.
Remove the eggs from the pan and let them cool.
Peel the eggs and cut them in half, trimming the ends so they stand upright.
Prepare the filling
Dice the chicken, ham, and beetroot into tiny pieces.
Chop the yolks and mix them with the diced chicken, ham, and beetroot.
Serve
Wash and dry the lettuce, then shred it finely.
Arrange the shredded lettuce on a dish.
Fill the egg halves with the chicken and ham mixture and place them on the lettuce to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main structure and the rich, binding yolk filling.
- Cold cooked chicken
- Adds savoury meat texture and bulk to the filling.
- Boiled ham
- Adds salty, savoury flavour and firmer texture to the filling.
- Beetroot
- Adds colour and a mild sweetness that contrasts with the savoury filling.
The step that matters
Boil the eggs for 10 minutes and cool them. Boiling for the full time sets the yolks fully so they can be chopped and mixed, while cooling stops further cooking and makes the eggs easy to peel and halve cleanly.

- Beetrootthe original
Fit is the average pairing score against egg, chicken, ham, lettuce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
