We're in the San Fernando Valley area and need help with milk pasteurization. We get breast milk for our baby and pasteurize but I'm having the worst time keeping the temp to 145F for 30 minutes on the stovetop! Can someone recommend a home pasterurizer or let us rent one from you? Or maybe there's a stovetop with temperature control so we can put our double-boiler on it and maintain that low heat. Sure could use your help and ideas! ThankS!
