Authentic Homemade Yogurt

Instructions

• On a work surface, lay four clean cotton towels in a cross pattern, each with one end overlapping a few inches in the center. Position a large baking dish or glass mixing bowl in the center of the towels.
• Set the plain yogurt on the counter to warm to room temperature while preparing the milk mixture.
• Combine milk and half-and-half in a large, heavy, non-aluminum pot. Heat over low to moderate heat, stirring constantly, until the mixture just comes to a boil. Immediately remove from heat and pour the mixture into the waiting bowl. Add 1 pint whipping cream for added richness.
• Allow mixture to cool to 112 degrees F (44 degrees C). Gradually pour 1 cup of the warm milk into the yogurt, whisking constantly. Return the yogurt-milk mixture to the bowl and stir well. Cover bowl with plastic wrap; wrap kitchen towels up and over the bowl, covering completely. Let stand at room temperature until firmly set, 8 to 12 hours.
• Refrigerate yogurt for several hours or overnight to chill completely.
