A word of warning about Paddle Fish black caviar. They sell it on all
those Exotic food websites and in some stores as an alternative to
Sturgeon caviar.
Please stay away form it. I had a misfortune of trying it at some
party and the taste was muddy and unpleasant. This fresh water fish
caviar is not even close in taste to cheapest sturgeon caviar let
alone osetra caviar.
Don't say I did not warn you

A few education points:

1. Beluga caviar is the most expensive ,but for no good reason really.
The fish is giant compare to osetra or sturgeon and amount of caviar
each Beluga produces should have made that caviar cheap, but
manufacturers BS consumer into thinking that Beluga caviar is the
cream of the crop...Not true, just good marketing.

2. Caviar is not to be consumed with Champagne. Champ. Wines are
acidic(dry) and kill the taste of caviar. Again the habit falls into
category of monkey see monkey do. Just because Champagne and caviar
both culturally belong to luxury food group does not mean they should
be consumed together (for super-Ghetto luxury feel).

3. B. Caviar goes well with light Lager beer, Coffee or Vodka.

4. Traditional way to consume B. caviar is on a French Baguette with
unsalted butter or with plain crepes(blini).
