I would use a tall cylinder with a handle, the size of a frying pan, instead of a lid, to allow the hot air to freely rise upwards, while also preventing it from splashing sideways. However, the cylinder is quite bulky. Perhaps there are simpler solutions? (Reducing the flame is not an option, as high heat is sometimes necessary, plus it splashes, albeit not as much, even on the lowest “flame”)
