Before a morning game drive, a couple of croissants in foil, laid in the V if a V8 Landy engine….after an hour they are perfectly heated.I used to put tins of beans and sausages on top of the van engine in winter. By the time I'd got to the next stop dinner was ready. Lol.
Stupid I know, but always thought there must be some way to warm food from the engine.
Not sure whether it’s still available but The Manifold Cook Book used to be available in SA.
