1) 1 quart plastic bags
2) a crank handle hand held cheese grater (amazon $10)
3) frozen seafood
My son (coral thief ak aspireringlobophile) and I used Langastinos ($!5 ) and seafood medally($25) both from Costco. The seafood medally has muscles, scallops shrimp and squid in it. we removed frozen muscles from shells.
then used cheese grater and mixed it into a bowel we tried to keep everything frozen and bagged it right away and kept the bags flat. I think we made 8-9 bags.
if I were doing it myself I would have stopped after 4 bags as I got tired of turning the crank but I could have egged him on for hours!! lol
when the mixture was in the bowel we could have added whatever we wanted, amino acids , selcon, blah blah blah. but this is a ton cheeper than any purchased food.
you'll have fun, the kids may not>>>>:)
