For a more flexible arrangement, two tripods supporting a heavier stick across the fire allows more than one pot to be used and makes it
easier to adjust the heat by moving the pots over different parts of the fire.
I carry a light chain with hooks on each end in each of my billy cans, which is useful for adjusting the height of a pot without having to fiddle about. It’s a bit of extra weight but saves a lot of bother.
Another very simple method of supporting your pots above the fire is to use a couple of pieces of angle iron. For this you will need supports at either side of your fire but as I usually make a
cooking fire between two largish logs this is usually no problem.
The bars can support quite large heavy pots or very small ones if needed just by moving them nearer of farther apart. The picture here shows four bars being used, once two are in place and level, another two can be laid across them for even more flexibility.
Here you can see a griddle placed across the bars which makes a good frying surface or can be used for griddle cakes and bannocks.
In a large camp a good size kettle is popular for keeping hot water constantly available but I normally favour a large pot that can be dipped into with a ladle, you can see it’s not boiling dry and can be used for other purposes too
