Don’t boil aggressively—a gentle simmer is your friend. High heat can make the skins split and the insides turn to paste. Use a heavy-bottomed pot and let the lentils relax into doneness.
How To Cook Lentils Perfectly And Use Them - Homemade Mastery
Test for doneness by crushing a lentil against the side of the pot with a spoon. If it yields easily but still holds its shape, it’s done. If it falls apart, you’ve gone too far. Taste as you go—that’s the secret of every good cook.
Add acidic ingredients like vinegar, lemon juice, or tomatoes only after the lentils are cooked. Acid can harden their skins and dramatically increase cooking time. Save the brightness for the final five minutes.
