Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Coconut milk: Adds richness and body, giving the soup a creamy, smooth texture.
Pumpkin: Forms the bulk of the soup; softens as it cooks and thickens the puree.
Lemongrass: Contributes a citrusy aroma that flavours the soup.
Shallots: Build a sweet, mellow aromatic base as they soften in the liquid.
Lime juice: Adds acidity that brightens the rich coconut and sweet pumpkin.

The step that matters

Simmer until the pumpkin is fully soft before blending. Pumpkin cubes that are not fully tender will leave a grainy or fibrous puree. Cooking until they break apart easily gives a smooth texture when blended.
