Make this classic Japanese lemon sour cocktail with just 4 ingredients!
You can pre-make the simple syrup and keep it on hand. Just mix 1 part sugar with 1 part hot water and stir until the sugar dissolves. Chill before using.
Large, clear, solid ice cubes will melt more slowly than weak, slushy ice. To further inhibit ice melt, use a frosted or cold glass.
