I highly recommend the Ohyama yogurt maker, especially if you're looking to make Dr. William Davis's L. Reuteri yogurt. For U.S. buyers, I suggest using a 120V to 100V step-down transformer to ensure compatibility. This yogurt maker is compact, lightweight, and easy to set up and use immediately. To make L. Reuteri yogurt, simply set the temperature to 38°C and let it run for 36 hours—no need for constant monitoring. Cleanup is a breeze, with no mess or fuss, making it far more convenient than using a sous vide or other bulkier, messier devices. Overall, this yogurt maker is an excellent choice for anyone wanting an easy and efficient way to make yogurt at home.
