I admit, the first time I used a pressure cooker I was a little afraid. I left my studio and stood on the other side of the door to avoid severe burning and disfigurement if my pot of legumes exploded. I called a friend to ask her if I was doing it right. But now I see the pressure cooker like a trusted friend who only wants to save me some valued time. So when I saw this lentil recipe in Veganomicon by Isa Chandra Moskowitz and the preparation time of 1 hour, I was so glad I had a pressure cooker to cut the time by nearly two-thirds, borrowing a technique from the Spanish and the Lentils with Chorizo Sausage Recipe (Recipe #342592). The first thing I did was skip the step where you sauté the onion and carrots for 10 minutes. It's unnecessary, and you'll find that my method makes a soup with a smoother, more pleasant consistency by cooking the vegetables whole or halved, then removing and pureeing them afterwards. My kitchen has a surplus of brown lentils, so those are what I used. I'm going to keep the brown lentils in the recipe because I don't know if French lentils require more liquid. One thing I want to try for next time, since I used bouillon cubes, is to break them up and try to dissolve them in step 2 rather than prepare the stock ahead of time, and I plan to cut down the salt next time. I find the best way to seed plum tomatoes is to cut them in half and sweep out the seedy parts with your index finger. The soup you'll get from this is addictively delicious and filling, and you'll feel like a genius for owning a pressure cooker.
