Summary
A temperance dairy-citrus drink showing how lemonade logic crossed directly into milk service.

Milk Lemonade matters because it shows the non-alcoholic side of bartending borrowing directly from mixed-drink technique and balance logic.

The extra sugar is not incidental; it is a practical anti-curdling adjustment built into the recipe.

Compared with plain lemonade, this is richer and more texturally managed rather than simply diluted citrus refreshment.

  1. Fill the glass with good cold milk and shake it well.
  2. Let it stand long enough for froth to form on top and spoon it off like eating ice cream.

Garnish: Froth on top

Ice: 0.5 scoop broken ice

This matters because it preserves another soda-fountain and temperance crossover where milk, citrus, and bar shaking overlap directly with mixed-drink service.

The spooned-off froth is the key service feature here.
