I am now the proud owner of a 7-liter Saratoga Jacks Thermal cooker. This is a thermal cooker that works on the same principle as the Wonder Oven. The 7-liter cooker will feed 6-10 people. Just like the Wonder Oven, it saves energy, and you can forget about it until you have your supper and it won’t burn.
The Saratoga Jacks Thermal Cooker looks like a crock-pot or slow cooker without the cord. Inside are two pans or cooking pots, one large and one small. The small one fits on top for rice or vegetables, or whatever you may want to cook with the main meal at the same time.
Like the homemade Wonder Oven, the rules are the same. You have to bring your food to a rolling boil for 5 to 10 minutes and then put it in your thermal cooker.
I put a whole chicken in the pot with carrots, celery, onion and spices to cook at 10:00 a.m., and by 5 p.m., it was done and ready to eat. I pulled the chicken off the bone and returned it to the pot adjusted the seasoning and added some barley to thicken the soup. I accompanied that with some Mexican cornbread and my dinner was ready. I did have to cook it a little longer to make sure the barley was cooked or I could have cooked the barley and then added it to the pot.
Be sure all of the ingredients are covered with liquid, and the food is thawed (even boiling frozen food may not thaw it completely). Frozen foods will cool the liquid down faster and delay cooking your meal. You may open it thinking it is ready to eat, but instead find the liquid cold and your food not cooked. So experiment and see what you like.
I know my husband has been a bit critical of thermal cookers in the past. He likes the Wonder Ovens because they are inexpensive and he is a bit of a miser, but I like this thermal cooker. It takes a lot less space to store, it is easy to clean, and I can use the inner pots to heat the food on my stove. When we go on a camping trip, it doesn’t fill the back seat.
