Slatko od šljiva — whole peeled plums held intact in clear syrup
Slatko od šljiva is defined by recognizable fruit: peeled plums remain whole or nearly whole in a clear, thick syrup instead of being mashed into jam. That difference determines the entire technique. The fruit must be firm enough to survive peeling, pitting and simmering, and the pan must be handled gently once the plums enter the hot syrup.
Firm ripeness is more useful than maximum sweetness here. Very ripe plums can taste excellent but tend to tear during peeling and collapse in the pan. Removing the stone through the stem end or a small slit preserves the round form. The method avoids a separate firming pretreatment, so fruit quality and gentle handling do the work of protecting the shape.
The sugar syrup is prepared before the plums are added. Starting with a clear syrup gives the fruit a stable cooking medium and makes it easier to judge concentration. Once the plums are in, stirring with a spoon can damage their softened surfaces; slow pan-shaking moves the syrup around them with less mechanical pressure.
The final syrup should coat a spoon lightly and thicken a cooled drop without setting like jam. It will become noticeably denser as it cools, so stopping early is safer than trying to reach the final texture over the heat. Lemon juice at the end adds brightness and helps balance the high sugar concentration.
After cooking, cool the slatko promptly and keep it covered at 4 °C or below for no more than 3 weeks. Freeze portions for longer storage, then thaw them in the refrigerator. Serve one or two intact plums with enough syrup to coat them; the shape of the fruit is part of the finished dish, not merely decoration.
