  1. Fill a cocktail glass with fine shaved ice and lay a slice of lemon on top.
  2. Pour kummel over until the glass is full.

Garnish: Lemon slice.

Ice: Fine shaved ice

This is a good example of liqueur service treated as a drink entry in its own right rather than only as a component.

The service depends on the chilled glass and lemon cap rather than mixing complexity.
