Sok od višnje — refrigerated sour-cherry cordial with a fixed 1:3 dilution
Sok od višnje is made here as a sour-cherry cordial concentrate with a fixed 1:3 dilution. Sour cherries bring more sharpness and tannic fruit character than sweet cherries, so the concentrate needs enough sugar to balance the fruit while still tasting recognizably tart once diluted. Removing the stones before maceration keeps the process controlled and the final drink free of pits.
Pitting is the longest active task, and doing it over a bowl keeps the valuable cherry juice with the fruit. The cherries then sit with part of the sugar for four hours under refrigeration at 4 °C or below. During that rest the fruit softens and releases enough juice to create a dark red macerating liquid before any water is added.
A brief simmer completes the extraction. The fruit does not need prolonged boiling, because the goal is a drink concentrate rather than a thick preserve. After straining, the remaining sugar and lemon juice are heated only until fully dissolved and the concentrate reaches a short even simmer. It should still pour as a thin syrup when finished.
Straining pressure controls the clarity. Pressing lightly captures the liquid and some fine fruit body; forcing the pulp through the mesh creates a cloudy, heavy drink. A lighter press produces a cleaner cordial that dilutes smoothly without a sediment of coarse cherry flesh.
Cool promptly, bottle in clean containers and keep at 4 °C or below for no more than 3 weeks. Freeze portions for longer storage and thaw them in the refrigerator. For one glass, combine 50 ml concentrate with 150 ml cold water; the fixed ratio gives a consistent balance of sour cherry and sweetness.
