Combine milk and nonfat dry milk in a large deep bowl.
Heat 12 minutes at FULL POWER or to boiling. Cool to
115F; monitor temperature with a microwave
thermometer. Combine starter with about 1/2 cup
cooled milk; mix lightly until smooth. Add milk
mixture to remaining milk, mixing until well blended.
Pour into warmed, large deep bowl. Place temperature
probe into milk; cover with plastic wrap. Insert probe
into oven. To incubate, heat to 113F on FULL POWER;
hold at that temperature 3 1/2 to 5 1/2 hours. (Reset
timer as needed) Chill. Yogurt will continue to
thicken as it chills. Makes about 4 cups. NOTE:
Drain liquid from yogurt after chilled. Yogurt will
become thin if liquid is stirred in.
