In a small bowl, sprinkle gelatin over the cold water (bloom the gelatin). Let it sit for 5 minutes until it softens and absorbs the water.
1 ½ tbsps Unflavored gelatin powder, 3 tbsps Cold water
Make freshly brewed coffee and set aside two cups. Let the coffee go warm, not scalding hot. The temperature should be very warm, but not hot. Stir in sugar until dissolved if you prefer.
2 cups Strong brewed coffee, 2 tbsps Granulated sugar
Add the very warm coffee to the bloomed gelatin mix and whisk for five minutes until fully dissolved and smooth.
Pour the mixture into a shallow dish or individual serving cups. Let cool slightly at room temperature. Refrigerate for at least 3–4 hours, or until fully set.
Cut into cubes and spoon into serving glasses. Drizzle with sweetened cream, condensed milk, or add to drinks before serving.
Heavy cream or half-and-half, Sweetened condensed milk, Vanilla ice cream, Whipped cream
