Admittedly it takes a little practice, mostly because it is such a new way of cooking but the GoSun stove is incredibly innovative – it combines an evacuated glass tube and parabolic reflectors. No fuel is required, it cooks only using solar power and it doesn’t even need to be summer. We have made muffin logs, sausages, baked potatoes, ratatouille, rice, pasta, meats and fish. You feel ahead of the game when using it, it’s light and portable and even after six months, it’s still fun. Perfect for boating. GoSun Sport is £200, other models available. www.gosunstove.com
