This document provides instructions for making homemade Greek yogurt using non-fat milk, active culture yogurt, and a double boiler. The milk is heated to boiling and then cooled to 100 degrees Fahrenheit before adding the culture yogurt. The mixture is then incubated for 25 hours in a warm place, drained, and strained through cheesecloth for 4-5 more hours before refrigerating. Optional additions of honey or fruit preserves can be added before serving.
