ABSTRACT:
A yogurt maker which requires only hot tap water at the proper temperature and a yogurt preparation to produce a natural yogurt without the need for an external heat source to promote incubation. The maker is constituted by a can which houses a Dewar flask, the can having a removable cover provided with a chromatic liquid crystal cell that serves to test the hot tap water to be sure that it is at the correct temperature before it is poured into the flask to be mixed with the yogurt preparation. The hot water mixture is maintained by the flask at the incubation temperature for a period indicated by a scale on the cover, which scale is settable relative to start and stop points on the can. Upon completion of incubation, the flask containing the yogurt is withdrawn from the can and refrigerated.
