What is a Thermal Cooker?
A thermal cooker has its roots in the hay box. By using vacuum insulation in this thermal cooker you have a slow cooker that does not need any power.
The energy saving thermal cooker can save up to 80% on cooking costs and is ideal for the home, caravan, boat, camping or just a day out. With just 10 minutes spent in the morning a thermal cooker can produce a hot meal when you get home and it won’t be burnt even if you are a little late.
Once you have a thermal cooker you will find that you use it every day for it can cook soups, main meals, puddings, cakes and bread.
For cooking two things at once most thermal cookers have two pots. Sometimes one will sit on top of the other or in the case of thermal cookers such as the Mr D's Thermal Cooker the top pot hangs from the rim of the inner pot. The main advantage this has over the two pot type is you can if cooking for a large number of people use the inner pot on its own.
How to use a Thermal Cooker.
Put all the ingredients into the inner pot and bring it to the boil. Once boiling reduce the heat to bring the contents to a simmer. Simmer for 10 to 15 minuets (depending on the recipe instructions). Once the simmering time is complete take the inner pot, off the stove and put it into the outer pot.
There is no need to plug in any power cord. The food will continue its “thermal cooking process” using the retained heat. After the required time (e.g. rice 30 minutes; chicken stock 2 hours; beef brisket 3.5 hours), just open the outer pot, and a nutritional and flavourful meal is hot and ready.
The thermal cooker has excellent heat retention capacity; the food inside the pot can retain a temperature of over 60°C even after 6 hours.
Tamarind Pork Curry cooked in Mr D’s Thermal Slow Cooker
Thai food uses the freshest ingredients to give it that unique taste. Thai recipes use all five flavors: spicy, sweet, salty, bitter and sour, bringing them together in perfect harmony.
This pork curry is uses tamarind paste to give it the sour taste and fish sauce to add a salty flavour. It does not use coconut milk just chicken stock and water.
If you would prefer to use chicken or fish instead of pork the curry should work fine.

The Best Venison Chili – Cooked in Mr D's Thermal Cooker
My venison chili con carne recipe, cooked without power in an energy saving thermal cooker is easy and quick to prepare and can be made for supper any day of the week. The recipe can also be cooked in a slow cooker or crock pot but it with both of these methods, unlike the energy saving thermal cooker, it will need a power source for the slow cooking process. If you don’t want to use venison you could use beef, chicken or pork. For a vegetarian version you could substitute the venison for a selection of different beans and use a vegetable stock cube or my favourite a vegetable Knorr Stock Pot. I however put venison the top of my favourite chili list and it is certainly worth trying.
