Heated Snow’s (which did not come with instructions) @ 300F for 1 hour sealed in foil. Worked out perfectly.
I forget if I used foil or not but the 225F for 75mins per Franklin’s instructions was not sufficient to soften the fat completely for the jiggly consistency.
Make sure you watch the Franklin’s carving video before you dig in. You REALLY don’t want to slice it incorrectly …
