Here’s the wild part: red lentils absorb twice their volume in water during cooking. A cup of dry lentils (about 200 grams) will drink up roughly 400–450 grams of liquid. That’s like a tiny, lentil-sized camel. And they do it in 15–20 minutes flat—no overnight soaking required.
This is why your pot of red lentil soup can go from “saucy” to “stew” in the time it takes you to answer a text. Pro tip: Always start with a little more liquid than you think you need. You can always boil off extra water, but you can’t un-mush a mushed lentil. (Unless you’re a wizard, in which case, please share your secrets.)
What About Rinsing? (Don’t Skip the Spa Treatment)
Before you even think about water ratios, rinse those little gems in a fine-mesh strainer. Red lentils often come with dust or tiny stones that want to ruin your dinner. Rinse until the water runs clear—it also removes excess starch that can turn your dish into wallpaper paste.
A quick note on rinsing: it adds a tiny bit of water to the lentils, but don’t worry—it’s negligible. Think of it as a pre-game warm-up. They’re just getting their toes wet.
