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 milk.
Bring the remaining milk to a boil, then stir in the flour mixture.
Add the salt and butter, then let it cool.
Assemble and bake
Mix the minced ham, parsley, and thyme with the egg yolks, then fold in the beaten egg whites.
Grease a skillet and pour in the mixture.
Bake in a preheated oven at 400°F (200°C) until set.

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, and yolks add richness and set the custard-like structure.
- Flour
- Thickens the milk into a smooth base that holds the omelette together.
- Sweet milk
- Adds moisture and tenderness, diluting the egg so it stays soft rather than rubbery.
- Butter
- Adds fat for richness and a softer texture in the finished omelette.
- Minced ham
- Contributes savoury flavour and salt-cured aroma throughout the omelette.
The step that matters
Folding in the beaten egg whites. Whites hold air only when beaten to stiff peaks and folded gently; stirring them in deflates the foam and leaves a dense, flat omelette.
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.
