A soboro is rather like furikake, except that it's moister. It's used like furikake in many situations - sprinkled onto rice, folded into other things like eggs, and more. Soboro can be made of ground meat, flaked fish (though fish soboro is often called oboro instead), or egg (egg soboro is often called iri tamago, just to keep you confused!) Meat soboro (niku soboro) keeps for about a week in the refrigerator, and freezes beautifully, making it a great bento johbisai or staple for the omnivore.
