Why it works: Asparagus and soy milk share more aroma than cooks usually use. They rank in the top 9% of all ingredient pairs, and 5 recipes mention both. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus tips
- Provide the main vegetable flavor and, once pureed, the soup's body and color.
- Soy milk
- Forms the liquid base that gives the soup its creamy moisture.
- Flour
- Thickens the soup as its starch absorbs liquid and swells when heated.
- Vegan margarine
- Adds fat for richness and carries the flour to form a smooth base.
The step that matters
Whisk the soy milk in slowly. Adding liquid gradually while whisking spreads the flour's starch granules evenly so they hydrate without clumping. Adding it all at once often leaves lumps that are hard to remove later.
