  1. How much water should we add to the gelatin? A TBSP?

  2. 2 Cups Strong Hot Brewed Coffee or Espresso
    2 tbsp Water

    Am I reading it correct?

    • LowCarbingAsian

      Hi Cheng – sorry, the wording is a little confusing! It should be 2 Cups Strong Hot Brewed Coffee (or espresso equivalent, which would be 2 espresso shot plus water). The 2 tbsp of water is for the gelatin and has nothing to do with the coffee itself. Hope that clears that up!
