Do you want to try a beetroot cooler in the summer heat like in a restaurant? It is not difficult at all, the main thing is to serve it beautifully. This portion in the restaurant costs 4 euros, so we cook at home! You can whip up a beetroot-kefir smoothie for one serving on trial or just for the family. Pickled beets can be safely stored in the refrigerator for several days under the lid.
