Admittedly, I've never used the crockpot very much, but a few weeks ago I tried a recipe for boneless skinless chicken breasts that I found here, and it was a tremendous disaster.
This morning, I gave it one last try, contemplating how to ditch the thing if it didn't produce an edible dinner. I made a beef stew, following some instructions here, and it turned out very, very well. Of course, I didn't follow the instructions exactly...
I tossed the stew meat with kosher salt, pepper, and flour, and browned it in a little oil; threw it in the pot with chopped carrots, an onion, a little celery, and a few turnips, along with some well-drained canned tomatoes.
Then, since I should have been showering and getting to my dreadful staff meeting, I made a little roux which I let brown somewhat, then added 1/2 cup merlot and a teaspoon or two of Tone's beef soup base (evil, I know, but oh-so helpful).
I managed to make some mashed potatoes before my children raided the fridge, and it made a wonderful, comforting dinner for a chilly rainy day. I couldn't stop eating it.
