iacisrmma – I know bliyos is not grease. I thought it was the grease they were selling and not the bliyos, but I guess I was wrong. That was just my assumption and I wasn’t sure about it (I think I made that clear; I hope so).
Thank you for the correction. I hadn’t thought that you could sell blius since it’s not a real thing. How can the goy take the blius from the pot? Or does it mean that he has permission to use the pot and thereby take the blius that is reabsorbed into the food being cooked? How can we let a goy use our pots?
