Ritz Old-Fashioned recipe

Rim an old-fashioned glass with lemon juice and caster sugar. Place a teaspoon-sized sugar cube into the glass, and saturate with angostura bitters. Fill the glass three-quarters of the way with broken ice, shake other ingredients (except soda) and strain into the glass. Top with a small amount of soda water if desired. Add two cherries on a stick, garnish with half slices of orange and lemon, and serve.
