If you want to stop making kefir for a while, take your grains and put them in a small glass container. Cover the grains with fresh milk to them and seal the container. Add the container to the fridge. I’ve left my grains like this for months – I just try to replace the milk every few weeks. Now, while it’s simple to make, store-bought kefir tends to be less sour than homemade. There may be an adjustment period for yourself or your family to get used to the new taste. One way to ease the transition is to make kefir smoothies! Here are three great smoothie recipes that you can use to get everyone used to the new flavour.
