When I started following Trim Healthy Mama, the amount of greek yogurt I ate quickly grew. Its a quick and easy source of protein. However after paying $5+ for a quart my wallet started to hurt and experimented with making my own. Many versions later I have developed a system that works consistently for me and yields wonderful creamy and delicious results.
- A gallon of milk
- 1/2-2/3 cup of plain yogurt
- Candy thermometer
- Stock pot large enough to hold the milk
- Colander and bowl that fits underneath
- Flour sack dish towels
- Pour the entire gallon of milk into the stockpot and place the candy thermometer on the edge.
- Heat on very low/low for 1-2 hours. Make sure that its low enough not to burn the bottom of the pan. You are looking for the milk to reach 180 degrees.
- Pull off the hot burner and let cool to 110/115 degrees.
- Stir in plain yogurt. Cover with lid and place in oven with light turned on.
- Leave for 10-14 hours. (No touching! Don’t open the oven door. I find it best to do overnight)
- Place colander over bowl and line with flour sack dish clothes. Pour yogurt into colander. Do not scrap the bottom, you loose a little bit of yogurt but it prevents weird bits of scorched milk in your yogurt. Place in refrigerator.
- Strain for 4-6 hours until yogurt looks/feels like thick greek yogurt.
Tips and Notes:
- The higher fat content in the milk the more yogurt you will yield and the creamier it will be. Many versions I have seen use whole milk for this reason. I personally use 1% as to have a creamy taste but keep the fat content at a minimum. One gallon of 1% milk makes 1.5-2 quarts of greek yogurt for me.
- I start the milk heating in the evening and place it in the oven before going to bed. It sits overnight and sometimes to lunch (depends on how busy the morning is). Yogurt is strained until lunch or when we get back from work.
- This does produce plain yogurt, however we find this best for our family so that we can use different sweeteners depending on the person.
- I found flour sack dish clothes at Target but they are widely available. I tried many version of clothes to strain the yogurt and this is by far the best. Don’t use cheesecloth, you loose lots of yogurt and its crazy to clean (had to throw mine out).
