01 - Pour whole milk into a saucepan and heat over medium heat, stirring occasionally, until temperature reaches 180°F. Monitor carefully to prevent scorching.
02 - Remove saucepan from heat and let milk cool down to 110°F. This temperature is optimal for activating the live cultures.
03 - Whisk 2 tablespoons of cooled milk with the yogurt starter in a small bowl until completely smooth and well combined.
04 - Pour the starter mixture back into the saucepan of cooled milk. Stir gently but thoroughly to distribute the culture evenly throughout.
05 - Transfer milk mixture to a clean container, cover, and wrap in a towel or place in yogurt maker. Let culture undisturbed for 6 to 8 hours in a warm location until set.
06 - Line a strainer with cheesecloth and set over a bowl. Pour the set yogurt into the strainer. Refrigerate for 1 to 2 hours until whey drains and yogurt reaches desired thickness.
07 - Transfer thickened yogurt to an airtight container. Refrigerate until ready to use. Keeps for up to 2 weeks.
