A small cafe on the edge of the maasai mara reserve in S.W Kenya that have switched to Cookswell Ovens, they bake about 80 loaves of bread a day along with cupcakes and then roast chicken and meat. per day they use appx 6kgs of charcoal for ALL the cooking. they also use a No 14 KCJ for boiling and frying needs.
6 people are now employed in a almost smokeless kitchen, before they bought a jiko, all thier cooking was done on a 3 stone fire and they used about 25kgs of firewood.
Cook, save money, eat well.
