Thanks a lot to all your replies. I won't take any chances I'll take the contents out of the tin. I'm big enough as it is and don't need any help on that front
I know that modern Army rations are bitb meals. However, during my time in't army it were all tins. Always cooked in the tin, but seldom ate from one. I'm none the worse for it. Other than my pants getting smaller and my tops getting bigger. I'm perfectly fine. Mind you, my stage show on a sat night as Thelam louise is taking on a more realistic stance of late.
wow you can still get goblin products? they used to do a range called goblin reddydins: -We regulary heat tinned food in the can when we do day walks. I find tinned food too heavy for camping. The kids favorite is sponge puddings that are designed to be heated in the can. The lid is taken off and then placed back on, the contents can burn if placed in too hot a fire. I tried a goblin meat pudding but they are really nasty. Lidl ravioli is very nice. As long as the food isn't over heated I can't see a problem, burning however can lead to a noticable metal taste, which I can see as maybe harmful.
