What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use overripe bananas for maximum natural sweetness and a creamier texture.
- 2Let the frozen berries sit at room temperature for 2 minutes before blending to reduce blender strain.
- 3Scrape down the blender sides once midway for a uniform consistency without lumps.
- 4Add chia seeds directly to the blender—no pre-soaking needed since kefir is thin enough.
- 5Serve immediately after blending; the chia seeds will thicken the smoothie over time.
- 6For a thicker smoothie, use only 1 cup of kefir and add a splash more water if needed.
