Martha, I don't do pasta in the Crock either. It always gets overcooked. Ew.
I made a simple scalloped potato hotdish last night, 1 box potato mix, 1 can corn (drained), some diced ham, and diced fresh bell pepper. Nothing frozen, 1 cup of milk from the fridge, plus cold ham. It also had 2 cups hot water. I set it on low the first hour and the pot was barely warm. I turned it to high and it took about 2 hours to finish. The potatoes were cooked but the sauce hadn't thickened as much as it should have. It needed less water because of being cooked in the Crock, I guess. In the future I'll try starting it on high, then turning to low once it's boiling. I can also preheat in the camper's micro if the Crock will fit into it, just to move things along a little.
It will take some experimenting but I'm sure I'll eventually get used to using it. I was surprised how long it took to get warm, though. The element in it must be very small.
Maybe I'll try cream cheese chicken in it tonight. That's an easy camping meal with baked potatoes and leftover pea salad. Not much work for me!
