Dr. Pepper’s Digestive Tonic Syrup

Charles Alderton, a pharmacist at a Waco, Texas drug store, liked the way all the fruit syrup flavors smelled mixing in the air and built a 23-ingredient formula from the medicinal dispensary where he worked. Early ads made no attempt to hide it: “aids digestion and restores vim, vigor, and vitality.”

Ingredients (makes about 3 cups syrup)

  • 1 cup prune juice
  • 1/4 cup each licorice root and sarsaparilla root decoction (simmer 1 tablespoon root in 1 cup water 20 minutes, strain)
  • 1 vanilla bean, scraped
  • 1/2 teaspoon each ground clove and ground ginger
  • 1/4 teaspoon almond extract, 2 teaspoons natural cherry extract
  • 1 cup raw cane sugar, 1/2 cup water, 1 teaspoon fresh lemon juice

Method

  1. Prepare the licorice and sarsaparilla decoctions separately, strain, reserving 1/4 cup of each.
  2. Combine sugar and water in a saucepan, heat until dissolved.
  3. Add prune juice, both decoctions, vanilla seeds, clove, ginger, almond extract, and cherry extract. Simmer gently 15 minutes until slightly thickened.
  4. Remove from heat, add lemon juice, cool completely, and strain through fine mesh.
  5. To serve: stir 2 tablespoons syrup into 8 oz cold sparkling water over ice.

Prune juice has long been used for digestive regularity; licorice root was a standard digestive aid in Eclectic medicine. Refrigerate up to 3 weeks.
