Victorian Americans favored many different kinds of puddings for desserts, during all seasons of the year. One type was tapioca–which hasn’t changed much in the intervening hundred-plus years. See many similar recipes in vintage era cook books and newspapers; plain, apple, peach, (and early in the 20th century, caramel).
Milk Shakes, a frothy, cold beverage was all the rage in the late 19th century (though made without ice cream until the 20th century). Machines shook the beverage until the milk-fat whipped and the flavorings mixed in. Ice cream sodas and shave ice (first snow cones, sold as “snow balls”) became popular, too. Victorians, even in the Old West, enjoyed icy treats and drinks in the heat of the summer.
