 The earliest known Polish recipes for borscht, written by chefs catering to Polish magnates (aristocrats), are from the late 17th century. Stanisław Czerniecki, head chef to Prince Aleksander Michał Lubomirski, included several borscht recipes in his Compendium ferculorum (A Collection of Dishes), the first cookbook published originally in Polish, in 1682. They include such sour soups as lemon borscht and "royal borscht", the latter made from assorted dried, smoked or fresh fish and fermented rye bran. A manuscript recipe collection from the Radziwiłł family court, dating back to ca. 1686, contains an instruction for making hogweed borscht mixed with poppy seeds or ground almonds. As this was a Lenten dish, it was garnished, in a trompe-l 'œil fashion typical of Baroque cuisine, with mock eggs made from finely chopped pike that was partly dyed with saffron and formed into oval balls. An alternative recipe for the almond borscht replaced pickled hogweed with vinegar.
