Some plants only at low positive or small minus temperatures show their characteristic taste, for example, Grunokol’s leaf cabbage only frozen becomes sweet and especially tasty. In addition, lovers of thorny juice or liquor should collect wild fruits rich in vitamins only after the first frosts, when their unpleasant sour taste disappears, due to the high content of tannins. Tip: you can improve the taste of these blue berries, holding them for a couple of days in the freezer.
