The New York Timesreports that Petrossian is selling caviar in a cubes. The pressed caviar is made from farmed California white sturgeon.
Now, Petrossian is making pressed caviar from farmed California transmontanus, or white sturgeon. It looks like shoe polish and is spreadable, with an intense flavor. A slick of the spread works on toast with some fromage blanc.
Petrossian has also started making little cubes of pressed caviar and packing it in jars of oil. They can decorate canapés, left, or deviled eggs, or be tossed with pasta. The oil also takes on flavor and can be used for seasoning.
The caviar cubes, called the Caviarcube, cost $45 for 20 grams, which is about 16 to 20 cubes. They can be purchased on Petrossian's website.
