To peel the lime start by trimming both the top and bottom of the fruit. Place it on one end and slice the skin (along with the pith) downwards all the way around (see the photo below).
Place the peeled lime along with the rest of the ingredients in the blender (use less maple syrup to start with and if needed add more later) and puree until silky smooth. Enjoy chilled.
Notes
Raspberries: Use either fresh or frozen. You can also add blackberries into the mixture if you like.
I used coconut water but almond or hazelnut milk would work too.
Sugar: I added a bit of maple syrup into the smoothie but you can use another sweetener, such as agave or rice syrup and honey (for a vegetarian option).
Storing: Store in a jar/bottle and refrigerate for up to 2 days. Shake before use.
