Hi everybody! Tonight I tried to make a rabbit leg roulade using activa RM, but it didn't work well as before. I sprinkled activa on the deboned leg, then wrapped in plastic film and allow to set in fridge overnight, finally cooked sous vide. After the poaching step the roulade looked perfect, but when I seared it, it began to "unwrap".
My guess is that activa has lost effectiveness: I used it for the first time in March, then kept it in freezer in its own package well closed with tape as suggested on the package. Is this period too long to keep it? I know that activa spoils rapidly in presence of oxygen but I couldn't find how rapidly.
Thank you guys
