Why it works: Celery and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 3,467 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Potato Soup a LA Crewe
Ingredients
Directions
Make the soup
Melt 3 ounces of butter in a large stewpan over medium heat.
Add the sliced onion, celery, and veal.
Cook gently for 20 minutes.
Peel and slice the potatoes, then add them to the stewpan with the cooked vegetables and veal.
Pour in 1 quart of water, the lemon rind, seasoning, and 2 quarts of milk.
Simmer gently for 2 hours, stirring occasionally to prevent burning.
Finish and serve
Pass the soup through a fine sieve into a clean stewpan.
Keep the soup hot in boiling water.
Stir in ½ cup of cream.
Adjust seasoning to taste.
Serve with small croutons of fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during simmering to thicken the soup and give it body.
- Milk
- Adds richness and a smooth, creamy body to the soup.
- Butter
- Enriches flavour and fat content while the vegetables and veal begin to cook.
- Cream
- Stirred in at the end to add richness and a softer, silkier mouthfeel.
- Veal
- Contributes meaty flavour to the stock-like base of the soup.
The step that matters
Simmering for 2 hours with occasional stirring. Gentle heat over a long time lets the potatoes break down fully and the soup thicken evenly. Stirring prevents the milk and starches from scorching on the base of the pan, which would give a burnt taste.
