Why This Recipe Works (Quick Science)
Lentils cook quickly compared to beans because they don’t need soaking and have a thin seed coat. As they simmer, they release starch that thickens the broth, making the soup naturally hearty. Adding kale near the end keeps it tender but still bright and slightly chewy, balancing the creaminess of the lentils.
Common Mistakes
- Not rinsing lentils: Skipping this step can leave grit in your soup.
- Adding kale too early: It will overcook and turn mushy. Add it last.
- Using too little seasoning: Lentils soak up flavor, so taste as you go.
- Cooking on high heat: Lentils can split and get mushy; keep it at a simmer.
