Frozen Berry Milk Kefir Smoothie

This is the simplest way to enjoy milk kefir - blended with frozen berries into a thick, probiotic-rich smoothie that's best served icy cold. The frozen fruit creates the perfect texture, but here's a brilliant trick: pour excess milk kefir into ice cube trays and freeze. You'll always have kefir cubes ready to add to smoothies, creating an even creamier result.

Milk kefir is perhaps the most powerful ferment you can make at home. It's loaded with tryptophan, an amino acid renowned worldwide for soothing the nervous system. Kefir also contains active lactase enzymes, which is why even people with lactose intolerance often digest it with ease, and why it provides such effective support for digestive health.

Makes: 2 servings
Time: 2 minutes

Note - I often add half a frozen banana or for sweetness and creamier outcome

Ingredients

• 500ml milk kefir, well chilled (or use 400ml milk kefir + kefir ice cubes)
• 150g frozen berries (blueberries, raspberries, strawberries, or mixed)
• Optional: 1-2 teaspoons honey or maple syrup if you prefer it sweeter

Method

1. Place the frozen berries and milk kefir into your blender.
2. Blend on high until completely smooth and creamy - about 30-60 seconds.
3. Taste and add sweetener if desired, blending briefly to combine.
4. Pour into glasses and serve immediately while icy cold.

Tips

• Scale the recipe up or down using roughly 150g frozen berries per 500ml milk kefir
• Kefir ice cubes create an extra-thick, frosty texture - make them whenever you have excess kefir
• Use any combination of frozen berries you enjoy
• The tanginess of your kefir will vary batch to batch - adjust sweetness accordingly
• This smoothie is naturally thick - add a splash more milk kefir if you prefer it thinner

Why This Works

The cold temperature is essential - it masks any sharpness from the kefir's natural tang and creates a refreshing drink rather than a sour one. Frozen fruit does double duty, providing both flavour and the icy thickness that makes this feel like a treat rather than a health drink (though it's absolutely both).
