Slow cookers are great kitchen tools. They come in various shapes and sizes. I own a small, round one that has a capacity of 1.5 liters. I also have two oval-shaped ones: one is a 3.5 and the other is a 4.7 liter one. Yes, baking and cooking will happen much slower, hence the name slow cooker. But even if it does take longer for the food to get done, they are still great for saving on energy while cooking. Their consumption is really low. My smallest one runs on 120W, the medium one on 200W, and the larger one uses only 270W per hour. Compared to preparing a roast in the oven within 4 hours, my medium-sized slow cooker would still only use 1600W for cooking it within 8 hours.
True, slow cookers aren't everybody's cup of tea. However, if you haven't done so, why not give it a try? Maybe you could find one on sale, for half the price, or really cheap at an online store? Or else, you could ask your friend if she would lend you hers for a little while?
Stay tuned. I will post more ideas and recipes in the near future.
