Uh-oh! Sounds like you forgot to squeeze all the extra liquid out of the cucumbers before you started.  Luckily, there’s an easy fix — simply line a mesh strainer with some cheesecloth or a clean towel and set it over a bowl. Spoon the loose tzatziki in, then lightly cover it with plastic wrap and pop it in the fridge. Within about 12-24 hours, the excess liquid should’ve drained into the bowl, leaving you with perfectly thick and creamy plant-based tzatziki.
