Question: Is this product made in Japan?
Document: This is a well-made product. Kept food hot for half the day! I would recommend this highly if you do lots of potlucks and snack duty!
For people have busy life like me, home made stock was just a dream before, since I do not feel comfortable to let the slow cooker do the cooking for a whole day while i am gone (i only use slow cooker overnight when i am home).With tiger thermal cooker, now i can have nice home made stock:1. At night, put all the ingredient and seasoning and water into thermal cooker.
This is big enough for a big family.And functions just like what it says!I should have got this long time ago!Fast shipping too!
Overall it's good. I like to cook, especially soup & all kind of Vietnamese noodle soup, pho, etc. I use the thermal cooker for  overnight cooking of chicken bones, pork or beef neck bones to get the broth. The only thing that I don't like is the cover. It's falling off several times, but it's easy to put it back on.
I had 6 qt one and love it. It save energy, money and time. I decided to add the larger one.
After it reach boiling point, let it simmer for 15-20 minutes to make sure all ingredient reach desired temperature.2. In the morning, boil the stock again when you are preparing to go to work. Adjust taste of stock if you have time. the re-boiling and cooking during the day will ensure the good taste come out of all ingredient into stock.3. At night, boil the stock, and drain, then you will have great stock.
Answer: Yes
