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 ↓
Spiced-up Butternut Squash Soup
Serves 6Ingredients
Directions
Prepare the squash
Peel the squash with a vegetable peeler.
Cut the squash in half crosswise, then cut each half in half lengthwise.
Remove the seeds.
Chop the squash into equal pieces (about 2.5 cm/1 inch) and set aside.
Make the soup
In a soup pot or large saucepan, heat the oil over medium heat and add the onion, garlic and curry powder.
Cook, stirring for about 2 minutes or until starting to soften.
Add the chopped squash, broth and cilantro, if using.
Bring the mixture to a boil.
Once at a boil, reduce the heat to a gentle simmer, cover and cook for about 25 minutes or until the squash is very tender.
Remove from heat and let cool slightly.
Puree and serve
Ladle the soup into the blender in batches and puree until smooth. Hold the lid with a kitchen towel to ensure it doesn't pop off.
Alternatively, use an immersion blender and puree in the pot.
Stir in the pepper and serve with a dollop of yogurt if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butternut squash
- Forms the bulk of the soup and, once cooked soft and pureed, gives it its body and smooth texture.
- Onion
- Softens as it cooks, adding sweetness and savory depth to the base.
- Garlic
- Adds pungent aroma that mellows and deepens as it cooks in the oil.
- Curry powder
- Blooms in hot oil to release aromatic spice compounds that flavor the whole soup.
- Vegetable or chicken broth
- Provides the liquid that cooks the squash and carries the flavors through the soup.
The step that matters
Cook the squash until very tender before pureeing. Pureeing squash that is not fully softened leaves a grainy, fibrous texture, because the starch and cell walls must break down with heat before blending can make the soup smooth.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (butternut squash, onion, clove, garlic, chicken, pepper, yogurt):
- Cuminfits better
- Turmericfits better
- Thymefits better
- Parsleythe original
