What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use frozen berries instead of fresh to give the smoothie a thick, frosty texture without needing ice.
- 2If you don't have buttermilk, stir 1 tablespoon of lemon juice or vinegar into 1 cup of milk and let it sit for 5 minutes.
- 3For a thicker, pudding-like consistency, let the chia seeds sit in the buttermilk for 5 minutes before blending.
- 4Ripen your banana until it has brown spots—that extra sweetness balances the tart berries and buttermilk.
- 5Blend on low then gradually increase to high to prevent the blender from stalling on frozen fruit.
- 6This smoothie keeps in the fridge for up to 24 hours; stir or shake well before drinking as the chia seeds will thicken it.
Adapt it for your goals.
Dairy-free
Replace buttermilk with unsweetened almond or oat milk mixed with 1 tablespoon lemon juice, and use a dairy-free coconut or soy yogurt. Keeps the tang and protein, perfect for lactose intolerance.
Low sugarLow-sugar
Omit the honey and use an extra half banana (if ripe) or a monk fruit sweetener to taste. Great for those watching added sugar intake.
Extra proteinExtra-protein
Add one scoop of unflavored or vanilla protein powder and increase the buttermilk by 2 tablespoons to maintain a drinkable consistency. Ideal for post-workout recovery.
Green boostGreen boost
Blend in a large handful of fresh spinach with the liquids—the berries and banana mask the taste completely. A sneaky way to increase your vegetable intake.
