Mixed Berry Smoothie

The difference between a good smoothie and a thin one is almost entirely whether the fruit went in frozen.

Chia seeds add body and a little fat, which keeps a fruit drink from spiking and crashing an hour later.

A smoothie is a ratio, not a recipe: frozen fruit, a soft fruit for body, a liquid and something to slow it down.

Once that is clear, the specific berries stop mattering.
