Oh
I thought you meant the actual preperation of the rolls.
If you do a search for curing caviar you should be in good shape.
as far as I know it's the same process as caviar prep.( caviar- sturgeon ikura-salmon)
I think it's pretty much an easy task as well. You would have to 'rub' the eggs on a mesh screen to remove the outer membrane and any blood. Then you should rinse it in clean water. From here the methods all vary, and since I have not done this, I won't give you advise! lol I know it's salted. I guess sometimes it is soaked in Brine, sometimes it's hand salted by a master chef.
You'll have to look around for any more info. Mabye someone else will step up!
Brine is just pretty much salty water - specifically water that is completely saturated with salts. Historically used to preserve veggies , fish, and meats.
