    Default Keeping food cold/cool or hot - even cooking!

    As overlanders in Africa for some years now we feel that we can pass on some practical advice.

    We often need to keep food in the camping fridge in good condition over a couple of weeks (or more) even in ambient temperatures of 40 deg. C + sometimes in areas with no outside power source.
    Many others must have similar challenges - so some practical, non-technical advice:
    1
    Make sure that your batteries / power source is fully charged and in good working condition!
    We use a basic "fridge / freezer twin ", a (12v DC power source or 220V AC (Inverter) with a small solar panel and controller, together with alternator-sourced simplistic split charge unit.
    2
    Pre-freeze everything beforehand that you don't need to use in the first 48 hr or so on your trip. do this at home or at starting point where outside power is available and pack into the freezer compartment in the fridge. Do NOT pack into the freezer unfrozen !!
    3
    Pre-cool the camping fridge on mains power at home before leaving with contents for the first 2 days in the fridge section. together with 500 ml plastic bottles to containing potable frozen drinking water in the fridge section - as they defrost use them for water. Then refill - and by now you may have some space in the freezer section to put in one or two 500 ml "empties" in for freezing. Rotate between freezer and fridge section to keep optimal cooling with minimum power loss.

    Sometimes you need to keep cool stuff cool inside a vehicle in high ambient temperatures for some hours - think sparkling water, cold drinks, beer, whatever,
    Especially relevant when you may not be able to exit the vehicle due to regulations or conditions.
    We have a practical solution for that too.

    Now we come to the second part:

    Sometimes you need to keep things hot or [U]cook[U] with minimal use of power or gas - we have a practical solution for that too.

    Anyone interested contact me by PM.

    Use a cushion cooker (call it what you will) - think a modern version of the old time "haybox" which was used by the Voortrekkers in their wagons when "on trek".
    The original was a box filled with dry grass as insulation into which the pot containing the food was put and then enclosed.

    The modern version:
    A pair of specially shaped cushions (to accept a pot inside when one is placed over the other) filled with polystyrene beads for insulation.

    So what you do first (on your normal stove or fire) bring your food to the boil sufficiently to get the heat through into the core if solid, or boiling point if liquid. Then place the pot inside the cushion tamping down the top to reduce heat loss through the interface between the top and bottom portion.

    It will continue cooking for up to 3 hours depending on circumstances and nature of the meal.
    Another plus is that a stew or similar content will not spill if in the bag on the back seat while travelling (OK - NOT on a grade 3 + 4x4 track!!!!)
    Oxtail, rice, vegetables etc. cooked in there are FANTASTIC. (Also no turbulence so veggies keep their shape and do not totally disintegrate into "mush".)

    It can also be used to keep your cold drinks or water COLD inside the car even when ambient is over 40 deg.c.
    Just cool or freeze first then put into the cushion.
    Obviously you should not freeze something that you wish to drink! So we normally use 500 ml water bottles pre-frozen (one at a time is enough to put in with the pre-cooled drinks.

    Handy in game areas where you are not permitted to exit your vehicle.

    Of course if you want some hot water for coffee then uuummmm - remember the good old thermos flask? Yes.
