Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Ham Omelet
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Beat the eggs separately.
In a small bowl, stir the flour into ¼ cup of the sweet milk.
Boil the remaining milk, then stir in the flour mixture.
Add the salt and butter, then let it cool.
Make the omelette
Mix the minced ham, parsley, and thyme with the egg yolks.
Fold in the well-beaten egg whites.
Grease a skillet and bake in a 400°F (200°C) oven until set.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Whites trap air for lift, while yolks add richness and help the omelette set.
- Flour
- Thickens the milk into a smooth base that holds the eggs together.
- Milk
- Adds moisture and softness, keeping the cooked omelette tender.
- Butter
- Adds fat for flavour and helps keep the omelette from sticking.
- Minced ham
- Provides savoury flavour and salty richness throughout the omelette.
The step that matters
Folding in the egg whites. Beaten whites hold air bubbles that give the omelette lift. Stirring or pressing them too hard deflates the foam, so the result turns dense and flat.
Swap the thyme
How well each one fits the dish's main ingredients (egg, milk, flour, butter, ham, parsley):
- Nutmegfits better
- Capersfits better
- Tarragonfits about as well
- Thymethe original
Fit is the average pairing score against egg, milk, flour, butter, ham, parsley. Candidates are from the same food group and used in at least 100 recipes.
“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.
