How would you make Homemade Bran Cereal Flakes (Three Ways), Homemade Corn Flakes Cereal, and Step aside, Cocoa Puffs... There's an easy (healthier) homemade version in town in an non-electric kitchen?
How about the corn flakes?I think you could mix the chocolate puff one by hand, otherwise there are hand crank food processor. As for an oven I don't know.
As for the bran flakes I would use a grain mill to crush the almonds and the wheat bran then mix the rest in. Although mixing the water would be difficult the hand crank processor might work.
