Pisco Sour vs. South Side

Both have lemon juice and simple syrup. Only the Pisco Sour has pisco and egg white; only the South Side has gin and mint. In parts, a Pisco Sour is 3 pisco, 1½ lemon and 1 syrup; a South Side is 4 gin, 2 lemon and 1 syrup. By volume, the Pisco Sour is 55% spirit, 27% citrus and 18% syrup and sugar; the South Side is 57% spirit, 29% citrus and 14% syrup and sugar. That makes them close cousins on the ratio map.
