Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow. (James 1:17)
(14-oz.) cans sweetened condensed milk
T. plus 1 t. vanilla extract
cups fresh or frozen blueberries
Combine first 3 ingredients, mixing well. Pour mixture into 1-gallon ice cream freezer container. Follow manufacturers instructions for operating the ice cream maker. When machine has stopped, drain the melted water from the bucket and repack with more ice and rock salt (3 parts ice to 1 part rock salt.) Cover with heavy towel and let set undisturbed for about 1 hour to "season". Stir blueberries into ice cream mixture just before freezing. Serve immediately or store in freezer. Makes about 2½ quarts.
