The Lekvárium building is almost a hundred years old. The essential equipment for making plum jam can be seen in the courtyard of the renovated farmhouse: the ovens and the boilers, which are also put into operation when the plums are ripe. A traditionally furnished peasant kitchen welcomes visitors in the building. The museum tries to introduce the tradition of making jam to visitors.
A native plum variety grows in this region, the Penyigei plum (popularly known as “nem tudom plum”). This plum practically grows wild, requires little care even in gardens, has small fruits, does not pit, has an ash-blue skin, yellow flesh, and is sweet and aromatic. Its fame extends beyond the country’s borders. Plum jam without sugar or preservatives, the “black gold of Satu Mare”, is made from this plum variety.
