Yoghurt in all kinds of flavours and textures can be bought at the supermarket, but freshly made yoghurt is both tasty and nutritious. It's simple to make homemade yoghurt in a yoghurt maker. Doing so allows you to choose whether you will make full-fat or low-fat yoghurt and what other ingredients you will add to the finished product.
Heat 1 quart of milk in a large pot. Use a cooking thermometer to make sure the temperature of the milk never goes above 85 degrees C. This will prevent the milk from burning.
Spoon 2 tbsp of plain yoghurt into a bowl and allow the yoghurt to come to room temperature. This yoghurt will be the starter for your new batch of yoghurt, made with your yoghurt maker.
Allow the milk to cool to room temperature. Turn on the yoghurt maker and allow it to warm up as the milk cools.
Mix 1/4 cup of nonfat dry milk powder into the milk at room temperature. Nonfat dry milk adds more nutrients to the homemade yoghurt. Stir in the 2 tbsp of plain yoghurt.
Pour the yoghurt liquid into the yoghurt maker cups. Start the yoghurt maker so that it begins processing the yoghurt mixture. Processing may take up to eight hours, depending upon the yoghurt maker.
Chill processed yoghurt in the refrigerator for a few hours, then eat.
Add chopped fresh fruit to chilled yoghurt or flavour with vanilla flavouring. Use 2 tbsp of the new batch of yoghurt as starter for the next batch. Always follow the directions on your yoghurt maker.
Clean the yoghurt maker well so mould and bacteria can't grow in the containers.
