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
Beat the eggs separately.
In a saucepan, bring the milk to a boil. Stir in the flour until smooth.
Add salt and butter, then let the mixture cool.
Make the omelet
Mix the minced ham, parsley, and thyme into the egg yolks.
Gently fold in the beaten egg whites.
Grease a skillet and pour in the mixture.
Bake
Bake in a 400°F (200°C) oven 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 trapped by beating provide lift, and the yolks add richness and structure as the omelet sets.
- Sweet milk
- Provides the liquid base and moisture that keeps the omelet tender as it cooks.
- Flour
- Thickens the milk into a smooth base that helps the omelet hold its shape.
- Butter
- Adds fat for richness and a softer, more tender texture.
- Minced ham
- Adds savory flavor and salt-cured taste throughout the omelet.
The step that matters
Gently fold in the beaten egg whites. Folding rather than stirring keeps the air bubbles in the whites intact. Those bubbles give the omelet its lift, so deflating them leaves a dense, flat result.
Swap the thyme
The recipe marks thyme as optional. 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.
