I use my mix for my FW and SW fish as well so I use shrimp, canned peas and canned carrots, then gelatin from the cheese cake/jello section at your store. I use a 1/2 pound of shrimp and a can each of peas and carrots. I blend the shrimp into a fine pulp and wait for the peas and carrots to heat up. Once its hot I blend the peas and carrots into the mix and add two pouches of gelatin mix right at the very end. Once the gelatin is mixed I pour it into flat seal-able containers at about 1/2"-3/4" think layer, about 3 containers most time. Now I put them in the fridge for a couple hours to setup the gelatin and then I put the extra containers I am not using in the freezer. The freezer makes the gelatin release so a quick heating in the microwave after thawing then a return to the fridge to set the gelatin again. Many people use some sodium alginate instead of gelatin, that seems to be popular as well. Here is a thread on home made food. viewtopic.php?f=27&t=1153&hilit=blend
