I have a small pack of cure#1 which reached its use by date in January. However, I did use it on a loin a few weeks back and it cured it okay. Yesterday I was given a fresh pack of cure#2 and when comparing the two packets side by side I realised that the pink colour of the cure#1 had completely drained, leaving it white. It has been kept in a dark drawer away from sunlight so its not been naturally sun-bleached.
Anyone know if this is an inbuilt indicator to show the lack of vigour or is it still okay to use. I'm about to cure a 2kg piece of leg of Pork using the injection/immersion method. Will the cure#1 be okay or should I substitute it with the fresh cure#2 and if so, would I have to re-calculate the amount ?
Yotmon.
