Okay, let's clear this up. You don't 'eat' caviar like a regular snack; you savor it. Traditionally, it's served very cold, usually on a bed of ice. Absolutely do NOT use a metal spoon; it taints the flavor. Get a mother-of-pearl or bone spoon. The classic accompaniments are blinis or lightly toasted brioche points, and sometimes crème fraîche. Keep it simple. The goal is to taste the caviar itself, not overpower it with other stuff. Anything else is basically an amateur move, tbh. Good luck with your first try! :)
