Whenever I buy seasoning for my summer sausage I usually buy enough to get free shipping if possible. When I do that I am unable to use the seasoning right away. It stay in a box in my pantry. After a period of time the seasoning gets harder then a rock. Is there something I can do to keep the seasoning from getting like cement? Is the seasoning still good? How do you break the seasoning down so you can mix it with the meat?
