01 - Pour milk into a saucepan and heat over medium heat, stirring occasionally, until it reaches 180°F. Watch 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 - In a small bowl, whisk 2 tablespoons of the cooled milk with the yogurt starter until completely smooth and well combined.
04 - Pour the starter mixture back into the cooled milk. Stir gently and thoroughly to distribute the cultures evenly throughout.
05 - Transfer mixture to a clean container, cover, and wrap in a towel to maintain warmth. Place in a warm spot or yogurt maker. Let culture undisturbed for 6 to 8 hours until set.
06 - Line a strainer with cheesecloth and set over a bowl. Pour yogurt into the strainer. Refrigerate for 1 to 2 hours, checking periodically until desired thickness is achieved.
07 - Transfer thickened yogurt to a clean airtight container. Refrigerate until ready to use. Keeps for up to 2 weeks.
