Plombir (plombière) ice cream bars were wildly popular in the Soviet Union. Based on an original French recipe and reminiscent of the Napoleanic era in its namesake, it was just one of many foods inspired by French haut-cuisine that gained popularity during the Soviet period.
Plombir was made of cream, milk fat, eggs, almond extract, and sometimes brandy. There were laws and governing bodies ensuring the freshness of the ingredients and the specificity of the manufacturing process. Many companies that made Plombir retained their nostalgic packaging, which reminds older folks of a more positive time.
