It's Lent, which means no meat or dairy, which means pasta, among other things. And once I experimented with cooking pasta in its sauce, and then I got a pressure cooker, well, you can guess the next step: pressure cooker pasta in sauce.
Sorry, I was hungry and forgot to take pictures. Next time.
First off: yes, it works. I used Kroger whole grain pasta; a can of diced tomatoes; some seasonings; a little wine (because it was a weekend, and I'm trying to use up the last of a box); and a little water.
Of course I had made a few attempts already that had gone wrong, so here's what worked. In the stovetop, I added pasta, diced tomatoes, seasonings (in that order) and then filled up the cooker with wine and water until the level of the liquid was almost to the top of the pasta.
I turned on the electric burner, set the cooker on it, and let the liquid reach a fast simmer, stirring all the while. When the liquid reached a fast simmer, I put on the lid. Once the cooker had reached full pressure I let it go about a minute and turned off the heat and walked away, leaving the cooker on the burner.
When the lid unlocked, I had perfectly-cooked pasta in sauce. Total burner time: 6 minutes.
This may not seem like much of a big deal, but with summer coming, you don't want to heat up the house, so instead of waiting for a pot of water to boil, and then cooking pasta for another 8 minutes, and cooking sauce in a separate pan, you'll be reducing your cooling bills significantly. And while this method may not be any faster (you still need the cool-down time), it's a lot less hands-on.
