After we used their solar ovens in Benin, Janet and I bought our own from the Centre Liweitari project and squeezed them into the car. (We also bought lamps they made there). I have tried various home-made solar oven experiments during my years in Africa, but this one gets much hotter.Since then rain has eased up a bit and we've been able to use the oven occasionally for our mid-day meals. Leah and I have been working on a new range of recipes to use in the cooker and anticipate free outdoor cooking during the hot season.
We brown the meat on the normal stovetop, then put rest of the ingredients with it in a black pot to 'slow cook' during the morning.
Rice cooked in the stainless steel bowl with a black lid (provided with the stove) takes only a few hours, especially near noon, and comes out fluffy and with a great flavour.
