I attempted to make a summer sausage. I mixed it with seasoning and let it cure for 3 days then stuffed into casing. Place in oven for 6 hours at 180. Removed it from oven and put it in fridge. After allowing to cool for several hours, I cut into it. When I did it was like a paste and crumbled. What did I do wrong? I did not poke holes into the casing (could that of been it). Help me out here.
