Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Mardi Gras Potato Soup
Ingredients
Directions
Start the base
Fry the bacon in a 2-gallon stockpot over medium heat.
When the bacon is about half cooked, add the onions, parsley, garlic, and celery; cook until the onions and celery are softened.
Cook the potatoes
Add 4 quarts of water to the stockpot, bring to a boil, then add the potatoes; cook for 40 minutes, covered, stirring occasionally.
After 40 minutes, spoon about half of the potatoes with liquid into a blender, purée until smooth.
Finish and serve
Return the puréed potatoes to the pot along with the salt, pepper, and half-and-half.
Cook for an additional 20 minutes, covered, stirring frequently.
Serve garnished with grated cheddar cheese and warm French bread; season to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red potatoes
- Break down into a purée that gives the soup its body and thick, creamy texture.
- Half-and-half
- Adds richness and a smooth, creamy mouthfeel to the finished soup.
- Bacon
- Renders fat that carries flavor and adds a savory, smoky note to the soup.
- Purple onion
- Softens and turns sweet as it cooks, building the soup's aromatic base.
- Celery
- Softens during cooking, adding a mild vegetal flavor and aroma to the base.
The step that matters
Adding the half-and-half. Dairy can curdle or scorch when it is boiled hard or left unstirred in a hot pot. Keep the soup at a gentle simmer and stir frequently while it cooks.
