EcclesCake, thank you for your reply. I was wondering if the texture would be affected by freezing too. The original container had no sell by date, its the same large container I've seen the deli using to fill the little tubs they sell. I have some small plastic tubs so will decant into those and pack tightly, perhaps cover with a little extra oil -and hope for the best. I love them so doubt they will last to the whiffy stage but will keep an eye out, thanks again for the reply.
