Ingredients

• 150g wild blueberries
• 300ml real milk kefir (plain, unsweetened, full-fat)
• 1 tbsp cold-pressed organic linseed oil (for omega-3)
• 1 tsp psyllium husks (for extra fibre)

Method

You’ll need: high-speed blender · sieve

1. Briefly rinse the wild blueberries and drain them well. Have the milk kefir ready so everything can go straight into the blender.
2. Put the blueberries in a high-speed blender with the milk kefir. Add the linseed oil and psyllium husks.
3. Blend everything finely until the smoothie is evenly creamy. If you like it thinner, leave it to stand briefly, then blend again.
4. Let the smoothie rest for a minute so the psyllium husks can swell slightly. This makes the texture a little thicker.
5. No need to season here – the mild tang of the kefir and the berries usually bring enough balance.
6. Pour into a glass and serve straight away, topped with a few whole blueberries if you like.

Good to know

A smoothie like this tastes pleasantly mellow and well rounded in the morning. Fruity, creamy and with a gentle tang. One of those easy glasses that still has substance.

Swaps

Wild blueberries → raspberries or blackberries (similar fibre content, with polyphenols too) Milk kefir → natural yoghurt or skyr with a little water/coconut water (more protein, milder flavour; yoghurt is still fermented) Linseed oil → 1–2 tbsp ground linseed or chia seeds (provides omega-3 plus fibre; whole foods instead of oil) Psyllium husks → chicory inulin (another type of fibre)

Allergens

Contains milk. Kefir and psyllium husks don't suit everyone equally well if you have sensitive digestion; for children, only in a suitable portion, and during pregnancy pasteurised kefir is considered the safe choice.

Frequently asked questions

What's special about wild blueberries?

Wild blueberries are usually smaller and darker than cultivated ones. They naturally provide polyphenols, especially anthocyanins, which give them their deep blue colour.

What nutrients are in milk kefir?

Depending on the milk and the fermentation, milk kefir contains calcium, protein, vitamin B12 and riboflavin, among others. It also brings microorganisms from fermentation, whose exact mix varies from product to product.

Why is there linseed oil in the smoothie?

Linseed oil provides alpha-linolenic acid, a plant-based omega-3 fatty acid. Worth knowing: the body converts only a limited amount into the long-chain forms EPA and DHA.

What should you know if you have a sensitive tummy?

That's individual: psyllium husks can feel quite heavy at first or make your tummy work harder, and not everyone gets on with kefir. If you're sensitive, start with a smaller portion.
