cooking after power down.

[bigpaul]

OH posed this question this morning and i would like to hear other peoples take on this. so OK the power is off and is going to be off for 48-72 hours and you want to heat up a can of soup, have a cup of tea..whatever...you dont have a fireplace or a log burner....so you get the camping stove out from where it is stored...you cant use it outside..its hammering down with rain ..total monsoon so you have to cook indoors..with some window or vent open....so here's the question...what do you put under the camp stove to stop it burning the worktop, table or whatever you put it on? you cant use asbestos anymore so what do you use??
