While everybody's preferences differ, a good chia pudding is neither too runny or too clumpy. Instead, it should be creamy and thick enough to resemble, well, a pudding. To achieve this, you'll want to transfer your pudding to an airtight container in the fridge and wait for at least one to two hours before eating it. If you want the pudding to have a really thick, velvety, and almost tapioca pudding-like consistency, consider leaving the mixture in the fridge overnight.
