Starter Care: The starter must be kept at room temperature in a glass container. Stir daily with a wooden or plastic spoon. Do not use metal utensils as they can damage the yeast culture.
Feeding Schedule: Typically, the starter is fed every 10 days by adding 1 cup each of flour, sugar, and milk. On day 10, use 1 cup of the starter for baking and give 1 cup to a friend, keeping 1 cup to restart the cycle.
Variations: This batter is versatile. Try adding raisins, coconut flakes, or orange zest for different flavor profiles. For a "Friendship Fruitcake" version, use canned peaches, pineapple, and maraschino cherries.
Storage: Wrap cooled bread tightly in plastic wrap or foil. Store at room temperature for up to 3 days, in the refrigerator for up to a week, or freeze for up to 3 months.
