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 ↓
Potato Soup Maigre
Ingredients
Directions
Prepare
Peel and chop the potatoes.
In a large pot, combine the potatoes, water, salt, sugar, parsley, thyme, and bay leaf.
Cook the soup
Bring to a boil, then reduce heat and simmer until the potatoes are soft and the water has reduced by half.
Remove the potatoes and herbs, and keep them warm.
Finish and serve
Puree the soup through a fine sieve or tammy.
Return the soup to the pot, add butter and milk, and bring to a boil before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large mealy potatoes
- Starch that breaks down during simmering to give the soup its body and thickness.
- Butter
- Adds fat and richness, giving the soup a smoother mouthfeel and rounder flavor.
- Milk
- Adds creaminess and dairy richness, softening the flavor of the potato base.
The step that matters
Pureeing through a fine sieve or tammy. Cooked potato cells break down into a smooth, starchy mass that can turn gluey if overworked. Pressing gently through a fine sieve keeps the texture silky rather than pasty.
Swap the parsley
How well each one fits the dish's main ingredients (potato, sugar, thyme, butter, milk):
- Cinnamonfits better
- Marjoramfits about as well
- Nutmegfits about as well
- Parsleythe original
Fit is the average pairing score against potato, sugar, thyme, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
