thanks, soyabean.
slow cooker = is it an electric slow cooker? If so, I have that already.
What I meant is whether a thermal cooker works in the same way as pressure cooker. I was thinking for cooking for the general family. like soups, porridge and stews. at the moment, I use pressure cooker, put on stove, reach pressure, then remove, and it continues to cook. I heard that thermal cooker is also the same function.. put on stove, but instead of reach pressure, it is reach sufficient internal heat, then remove and it continues to cook. in this way, it is energy saving. the benefit over pressure cooker, is that thermal cooker can be opened anytime.. unlike pressure cooker which can only be opened when pressure is reduced (for safety reasons).
a 6.5litre pressure cooker is selling at $279 now. but a 7 litre thermal cooker is selling at under $80. the price difference is very great. I'm used to using a pressure cooker, but have no experience with thermal cooker, so want to ask what the difference in function is, and which is better, or should I get both? my family uses pressure cooker very often (cooking chicken stock from bones, porridges soups and stews, and desserts too). We use it every other day...
