The liquid you choose is mostly based on your own preferences. I tend to choose unsweetened almond milk more often than not because we always have it available in our fridge. Any creamy dairy-free milk is a good choice, but water can also work. u003cbr/u003eu003cbr/u003eI like to use coconut water in berry flavored smoothies. If you like a really thick consistency, dairy-free yogurt would be delicious as your liquid.
