Powidl

Powidl(alsoporvidl,powidła,povidla, orpowidel) is aplum butter, a type offruit spreadprepared from theprune plum, that is popular in Central Europe. Unlikejamormarmalade, and unlike theGermanPflaumenmus(plum puree), powidl is prepared without additionalsweetenersorgelling agents.
Powidl is cooked for several hours, in order to achieve the necessary sweetness and consistency. The plums used should be harvested as late as possible, ideally after the first frosts, in order to ensure they contain enoughsugar.
InAustria,MoraviaandBohemia, powidl is the basis forBuchteln, powidl cake andGermknödel, but it is also used as a sandwich spread. Powidl will keep for a long time, especially if kept in traditional crockery.
Traditionally, large amounts of powidl to be used as a winter store and natural sweetener were prepared in late autumn during a communal event. Since constantly stirring the pot was exhausting work, people took turns, and did easier work in between turns. The Czech termpovidlais plural only (the Polish wordpowidłaas well).
Traditionally the plums were "overcooked," (to promote evaporation) in a copper kettle, or sometimes vinegar preserved, or even steamed.One recipe for "dark red plum jam" (povidl) begins with placing the plums in afermentation crockalong with sugar and cider vinegar, and letting the mixture sit for a day before cooking.Another recipe for "traditional Austrian plum butter" recommends roasting the plums in an oven  and then transforming thatcompote-like dish into jam.
Powidl is a key ingredient of the popular Austrian street foodpofesen, which is a jam-filled form of French toast.
Unlike with modern fruit spreads, the original method of long-boiling kills almost all germs while the water removal provides for high sugars content (above 70%), acting as a natural preservative.
In this the traditional method of production allows for a long shelf life even in unsealed containers. This property madepowidlunique among other pre-industrial fruit products available in the area.
The choice of prune plums, as compared to other sugar-rich fruit grown in the area, including other plum varieties, is their riping as one of the last fruits in the season, after the main harvest. The prune trees are less sensitive to cold, making them popular in harsher climate areas.PowidlandSlivovitz, being both products of the fruit with long and very long storage, allowed yearly prunes harvest fluctuations to be compensated readily.
The prune plums are naturally suitable for processing, compared to other late-season fruit. When ripe, the prune core separates from the shell easily, unlike with other plum varieties, and the fruit skin has little structural strength, dissolving while cooked.
The sturdier Apple or Pear fruit require mechanical core separation and either the removal or pre-processing of the tough skins before cooking. While such processing can be economical with modern machinery, it was a major challenge in the pre-industrial era or in a household setting.
The high-sugar content, combined with good availability and storability, madePowidlinto the general sweetener in many traditional recipes.
Before processed sugar became affordable with industrial production,Powidl/Povidlawas one of the main sweeteners in many local cuisines, alongside Honey.
Most commercial products sold asPowidl/Povidlaare made from dried fruit and fruit puree, using ingredients from not fully ripe fruits, then sweetened by processed sugar.
The original production recipePowidl/Povidlais still made under various markings like "organic", "traditional" etc. While a good indication is that traditionalPowidlmust not include any other ingredient but fruits, that itself is not a guarantee that the traditional long-cooking process was used. Cheaper method of mixing dried fruit with fruit spread and then cooking only shortly is commonly used in production.
The traditional methodPowidlhave a distinct bittery and soury taste from the over-cooking that causes a different composition of the product as compared to the short-cooked versions.
