The MRE heaters are designed for 'wet' food and MRE sized pouches
Yip, knew that.
, which are a different size to the UK meal pouches. The MRE food pouches are long and thin with less content, hence the design of the heater pouch. That is why it is sometimes necessary to use 2 heaters for a UK meal pouch in arctic conditions or when the meal is very cold.
Right, never used Uk rations so good info.
A dehydrated meal pouch needs boiling water added and then left to stand for 5-10 mins in order to properly reconstitute. I doubt very much that the heater could do this for you.
One way around this could be to add the water to the meal a couple of hours before use so that it can absorb lots of liquid but it then needs to be cooked lika a conventional meal. I have used roasting bags for this, they can be roasted or boiled so you can drop the bag into a pot with boiling water and this cooks the meal.
Good ideas. I have done this with fresh egg pasta. Did it for hillwalking. Re-heated it at the summit.
They are actualy a great addition to any bushcrafter's kit because you can empty canned food into a roasting bag at home and carry it in a sac safely for the day, saving weight and rubbish to be carried. It also keeps your pot clean and provides water for a brew and a hot meal at the same time.
I have even wrapped a tickled trout in a bag, packed it in grass and mud for a great steamed fish meal.
Yeas, the heaters are handy. Great for keeping hands warm well after the heaters has heated the food.
Thanks
