What is kastinys?
Kastinys is not cheese and not a simple sour cream spread. It is a hand-stirred dairy product in which sour cream and butter are joined into a smooth, airy mass.

It is flavored with caraway seeds, garlic, salt, pepper, or herbs and traditionally eaten with hot potatoes. According to the Universal Lithuanian Encyclopedia, it is a peasant food of Courland and Žemaitija, stirred with a wooden spoon in a clay bowl; once chilled, it was eaten during fasts and communal work gatherings, was widespread until the mid-twentieth century, and has been made again as a traditional dish since the beginning of the twenty-first century.
Žemaitiškas kastinys
Kastinys is most strongly associated with Žemaitija. The name Žemaitiškas kastinys is protected as a Traditional Speciality Guaranteed, emphasizing traditional composition and method.
The EUR-Lex specification stresses that the product's distinctiveness comes from the combination of sour cream, butter, soured milk product, spices, and stirring technology. Therefore kastinys cannot be exactly replaced by a simple mixture of sour cream and butter.
It is an example of regional dairy cooking in which luxury matters less than technique, temperature, and hand work.
The stirring technique
Kastinys is stirred with a wooden spoon or paddle. During stirring, butter and sour cream gradually join and the mass thickens.
Too much heat melts the fat and the mass separates. Too cold, and it is difficult to bring together.
Serving
The classic pairing is kastinys with hot potatoes. The potatoes warm the kastinys slightly and bring out the aroma of butter and sour cream.
It also works with rye bread, vegetables, or as part of a traditional appetizer table.
Recipe
How is kastinys made?
Kastinys is made by gently warming and stirring sour cream with butter so a smooth emulsion forms. The key is not to overheat and not to beat too aggressively.
Ingredients
Method
- Put the butter and a few spoonfuls of sour cream in a bowl over a very warm water bath so the mixture softens but does not melt.
- Stir in one direction with a wooden spoon, gradually adding the remaining sour cream.
- Mix in the sour milk or kefir, salt, caraway seeds, minced garlic, and pepper.
- Continue stirring until the mass becomes smooth, airy, and holds its shape.
- Serve with hot boiled potatoes.
Notes
If the mass separates, it was probably overheated. Work at a lower temperature and be patient.
Kastinys is a fresh dairy product, so keep it chilled.
