Hull the strawberries and pop them in your blender. Put the cardamom pods in a pestle and mortar and bash to open up the pods. Discard the green papery skins and grind the seeds to a fine powder. No pestle and mortar? Use a small bowl and the bottom of a jam jar or the end of a rolling pin to crush the seeds.
Add the cardamom seeds to the strawberries and spoon in the Greek style yogurt. Pour in 250ml cold water and add a few ice cubes. Blitz for a few mins till smooth.
Pour the lassi into 2 tall glasses and dust the top of each one with a little ground cinnamon just before serving (keep the rest of the cinnamon for your Banana & Turmeric Blaster).
