Rainbow Trout Roe Caviar (also known as Mykiss Ikura) is an inexpensive delicacy from Europe. It is harvested from the rainbow trout, which is farmed in Denmark. If you look closely enough, the medium sized beads have a tiny distinct orange eye on its translucent shell. The caviar has a bold taste and sticky texture, making it a great compliment for garnishing appetizers or hors d'oeuvres.
