Recipes for Mixed Drinks by Hugo R. Ensslin (1917, p.26) — Ensslin 1917
| 1 lime or half lemon | lime or lemon juice — Lime Juice or Lemon Juice | acid |
| 0.5 teaspoonful | powdered sugar — Powdered Sugar | base |
| 1 jigger | rye whiskey — Rye Whiskey | base |
| 1 piece | Orange peel — Orange Peel | garnish |
| 2 dashes | Grenadine syrup — Grenadine | sweetener |
- Shake well in a mixing glass with cracked ice.
- Strain and serve with a twist of lemon peel on top.
Garnish: Orange peel and lemon peel
Ice: Cracked ice
This matters because it preserves a named whiskey sour branch where grenadine and dual citrus options are built into the identity.
The orange-peel and lemon-peel finish is part of the service grammar rather than mere decoration.
