For a spicier, more complex flavor, use Mexican chocolate ice cream from a Latin market, melt a few squares of Mexican chocolate and blend it into the shake, or use the ordinary recipe with the following added ingredients:  ⅛ tsp (1 pinch) ground cinnamon ⅛ tsp (1 pinch) ground chiles ⅛ tsp (1 drop) vanilla extract Even if you aren't a coffee fan, a pinch of espresso powder will make the shake earthier and toastier. For a stronger mocha blast, blend in 2–3 teaspoons (10–15 mL) of the espresso powder instead. This pairs well with ½ teaspoon (2.5 mL) almond extract. Freeze a banana, a couple strawberries, or a handful of raspberries. Slice the frozen fruit into small chunks, then blend for a few seconds to mix the flavors together.
