windscreen

that said, I prefer alcohol stoves to solid fuel stoves. I have bullet-proof brass trangia alcohol stove as well as some home-made penny stoves.

IME, nothing beats a good hot burner such as my MSR Dragonfly. But for simplicity, I like an alcohol stove with the solid fuel stoves third.

I have had ok luck with a heavy foil windscreen or even digging/finding a hole or depression and using a foil cover on the cup/pot.

good luck
eta a bit of foil on the bottom of your pot will keep the pot clean
