There's never too much caviar, except when you're crossing the Russian border. Russia has strict custom laws regarding salmon roe and caviar. An individual may only carry a maximum of 250 grams across the border. Furthermore, the product must be factory produced, meaning packed in airtight glass or plastic. In other words, beluga caviar sloshing around in a Tupperware container won't get past the customs folks, so don’t buy any from markets to bring home.
