The Thermal Cook – January 2011 Newsletter

Setting up for our last show of 2010

Happy New Year and welcome to  my first monthly newsletter on Thermal Cooking.

Last year has been a difficult one for all of us but lots of people have seen the advantages of using a thermal cooker with its saving in energy and the ability to time shift meals. What does surprise people is that a thermal cooker uses less fuel than even a pressure cooker and unlike a pressure or slow cooker it allows you to eat when you are ready rather than you having to eat when the meal is ready.

In September due to the amazing number of sales at the Southampton Boat Show we ran out of Mr D’s Thermal Cookers and most of the accessories, so we were pleased to get more stock from our manufacturer in time for Christmas. By the time that they arrived we had a large number of back orders so December was very busy shipping cookers to customers in UK, USA and Europe so they would have them for Christmas.

Even with the new stock we are getting a bit low on the cake tins and top pots and have now placed another order which should be with us February/March, the start of our show season.

The feedback from customers who bought cookers at the Southampton Boat Show has been amazing. Although the majority of cookers bought at the Boat Show are being used on boats they are also being used for shooting parties, fishing, taking to work and rugby matches at Twickenham.

The new Thermal Cook iPhone appIn December we also released The Thermal Cook iPhone/iPad app. This has been very popular with an average of 100 downloads a week from all over the world. The app allows you to download both recipes and videos for watching later as well as keeping you up to date with The Thermal Cook Blog.

Each month I will be posting a recipe suitable for Mr D’s Thermal Cooker and this month it is a wonderful pot roast which is ideal for a Sunday lunch on a cold January day. I will also be giving a list of what is in season for each month. This you will find below.

What is Thermal Cooking:

For those of you who do not know what thermal cooking is here is a short introduction as to how it works and how it can save you up to 80% on your fuel costs.

How a thermal cooker worksMr D’s eco-friendly thermal cooker has its roots in the hay box. By using vacuum insulation (instead of bulky hay) in this thermal cooker you have a super efficient slow cooker that does not need any power once you have brought the food to the boil.

Mr D’s eco-friendly thermal cooker can save up to 80% on cooking costs and is ideal for the home, caravan, boat or just a day out. The inner pot can be used on gas, electric, ceramic or induction hobs. With just 10 minutes spent in the morning Mr D’s eco-friendly thermal cooker can produce a hot meal when you get home and it won’t be burnt even if you are a little late. Mr D’s Cookware also has a complete range of cookware accessories for use with Mr D’s eco-friendly thermal cooker. This includes a recipe cook containing over 80 recipes specially designed for a thermal cooker.

Mr D’s eco-friendly thermal cooker comes in two versions – the one pot and the two pot version. The two pot version has a second top pot that fits inside the inner pot and therefore means that you can cook two different items at the same time. The second top pot is only available from us in the UK.

Once you have Mr D’s eco-friendly thermal cooker you will find that you use it every day. It can cook soups, main meals, puddings, cakes and bread.

Step by Step:


Step by Step cooking with Mr D's Thermal Cooker


It is easy to cook with Mr D’s Thermal Cooker. For instances when making a meal put all the ingredients in to the inner pot and bring it to the boil. Once boiling reduce the heat, bring the contents to a simmer. Simmer for 10 to 15 minutes. When the simmering time is complete take the inner pot off the stove, put it into the outer pot and close the lid.

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 min; chicken stock 2 hrs; beef brisket 3.5 hrs), just open the outer pot, and inside a nutritional and flavourful meal is hot and ready.

Mr D’s Thermal Cooker has excellent heat retention capacity; when 3/4 full the food inside the pot can retain a temperature of above 60 degrees C even after 6 hours.


Advantages of Thermal Cooking:


  • Lets you take hot or cold food anywhere and keeps it at a safe temperature for hours.
  • You only need to spend a few minutes in the morning putting a meal together and it will sit in your campsite, caravan, vessel or home and cook itself while you are busy doing other things.
  • You do not need to change your cooking habits – you can still use your favourite casserole, crock pot, or slow cooker recipes.
  • The slow and gentle cooking ensures that meat stays super moist and tender while vegetables retain their shape, texture and colour.
  • The food cooks in its own juices so you are not throwing away all the goodness – the vitamins, nutrients and flavours stay in your meal.
  • The food inside can never be over-cooked so you will avoid scorching, evaporation, over boiling or bitterness.
  • You will save on energy as cooking on the stove is reduced to a very a short period of time.
  • You will save on washing up as there won’t be an array of saucepans, frying pans and serving dishes to clean up.
