Lemon and Coriander Greek Yogurt

Directions

1. In a Dutch oven, heat milk over medium heat until a thermometer reads 200°, stirring occasionally to prevent scorching. Remove from heat; let stand until a thermometer reads 112°-115°, stirring occasionally. (If desired, place pan in an ice-water bath for faster cooling.)
2. Whisk 1 cup warm milk into yogurt until smooth; return all to pan, stirring gently. Stir in lemon zest and coriander. Transfer mixture to warm, clean jars, such as 1-quart canning jars.
3. Cover jars; place in oven, turn on oven light to keep mixture warm, about 110°. Let stand, undisturbed, 6-24 hours or until yogurt is set, tilting jars gently to check. (Yogurt will become thicker and more tangy as it stands.)
4. Refrigerate, covered, until cold. Store in refrigerator up to 2 weeks. If desired, serve with honey.
