Chocolate Soda

From Fran Bigelow's book Pure Chocolate, this is a lovely drink, reminiscent of soda fountains.

3 Tbsps Chocolate Sauce
3 scoops vanilla gelato
Sparkling or carbonated water

1. In a tall glass mix 2 Tbsp chocolate sauce with 1 scoop gelato and mix to make a paste.
2. Carefully and slowly pour in sparkling water until the glass is half full - the water will react and foam up. Dilute chocolate ice paste in the sparkling water until uniform.
3. Add the rest of the gelato as balls, then drizzle with the remaining tablespoon of chocolate sauce.
4. Continue adding sparkling water until water is 3" from the edge, to leave room for the soda-fountain bubble.
