Trim the dry ends off the rhubarb sticks and chop the sticks into small chunks. Pop them into a blender. Pour in the almond drink and blitz till well combined. Pour the rhubarb mix through a sieve set over a bowl or jug and use a wooden spoon to press on the fibrous strands of rhubarb in the sieve to squeeze out as much liquid as possible. Discard the rhubarb strands. Pour the almond and rhubarb mix back into the blender.

Peel and break the bananas into the blender. Grate in the lime zest and squeeze in half of the lime juice. Tumble in a few ice cubes and blitz till smooth. Have a taste and add more lime juice if you like. Pour into glasses and serve.
