Add the frozen raspberries, cranberry juice, chia seeds, honey, lime juice, and almond milk to a blender in that order. Start with the liquids and softer ingredients at the bottom so the frozen fruit doesn't get stuck on the blades. Blend on high speed for 60-90 seconds until completely smooth and creamy—you want a thick, soft-serve consistency that holds its shape when scooped, not a thin drinkable smoothie. I like to pause halfway through and give the blender a shake to ensure everything is evenly combined, especially those chia seeds.
