Combine pineapple chunks, apricot halves, sliced peaches, maraschino cherries, brandy, and white sugar in a large glass jar. Stir gently with a wooden spoon until the sugar is combined.

Cover loosely and let stand at room temperature for 3 weeks, stirring at least twice a week.

Drain the fruit, reserving the liquid. The reserved liquid is the starter for Thirty-Day Friendship Cake.

Transfer the brandied fruit to an airtight container and refrigerate until ready to use.
