Ingredients

  • unknown Citric Acid (Provides tartness; exact amount not disclosed in the transcript.)
  • unknown Vanilla Extract (Adds sweet aromatic depth; amount not specified.)
  • unknown Lime Juice (Freshly squeezed if possible; contributes citrus note.)
  • unknown Coca Leaves (cocoa leaves) (Coca leaf extract (cocaine‑free) is legally imported for flavoring; exact quantity not given.)
  • unknown Caramel (Provides color and sweetness; amount unspecified.)
  • unknown Alcohol (neutral spirit) (Used as a solvent for flavor extracts; amount not disclosed.)
  • unknown Orange Cinnamon (Cinnamon infused with orange peel; exact proportion unknown.)
  • unknown Lemon Juice (Adds bright citrus flavor; amount not specified.)
  • unknown Coriander Seeds (Ground; contributes subtle spice; quantity unknown.)
  • unknown Nutmeg (Freshly grated; adds warm spice; amount not given.)
  • unknown Naroli (orange‑blossom extract) (Extracted from orange blossoms; exact amount not disclosed.)
  • unknown Phosphoric Acid (Merchandise 4; provides sharp acidity; quantity not specified.)
  • unknown Carbonated Water (Final diluent; amount depends on desired strength (typical 5‑6 parts water to 1 part syrup).)

Instructions

  1. Prepare Flavor Base

    In a medium saucepan combine citric acid, vanilla extract, lime juice, lemon juice, orange cinnamon, coriander, nutmeg, naroli, and the caramel. Add a small amount of neutral spirit (alcohol) to help dissolve the flavor extracts.

    Time: PT5M

    Temperature: Medium heat (about 150°F / 65°C)

  2. Incorporate Coca Leaf Extract

    Add the coca leaf extract (coca‑free) to the mixture, stirring until fully integrated. This step should be done off‑heat to preserve delicate flavors.

    Time: PT2M

  3. Add Phosphoric Acid

    Slowly drizzle phosphoric acid into the warm syrup while stirring. The acid will react with the other components, creating the signature sharp bite.

    Time: PT3M

  4. Cool the Syrup

    Remove the saucepan from heat and let the syrup cool to room temperature. Then strain through a fine mesh sieve to remove any solid particles.

    Time: PT10M

    Temperature: Room temperature (68‑72°F / 20‑22°C)

  5. Dilute and Carbonate

    Mix the cooled syrup with carbonated water in a ratio of roughly 1 part syrup to 5 parts water (adjust to taste). Use a soda maker or CO₂ charger to ensure proper carbonation.

    Time: PT5M

    Temperature: Cold (40‑45°F / 4‑7°C)
