01 - Pour milk into a saucepan and heat over medium heat until it reaches 180°F, stirring occasionally to prevent scorching the bottom.
02 - Remove from heat and let the milk cool down to 110°F. This takes about 15-20 minutes.
03 - In a small bowl, whisk 2 tablespoons of the cooled milk with the yogurt starter until completely smooth.
04 - Pour the starter mixture back into the cooled milk and stir gently to incorporate evenly.
05 - Transfer to a clean container, cover, and wrap in a towel. Place in a warm spot or yogurt maker and let culture undisturbed for 6-8 hours until set.
06 - Line a strainer with cheesecloth and set over a bowl. Pour in the yogurt and refrigerate 1-2 hours until thickened to desired consistency.
07 - Transfer thickened yogurt to a clean container. Refrigerate until ready to use.
