@twigg267 If you are looking for something similar to the Jimmy Deans with some heat go with the Holy Regular Pork Sausage, that is very close to the taste but it doesn’t have much heat. For some heat I would add some Xtra Hot Ground Red Pepper Shaker, just be careful with this as it is very hot! It’s suggested use is 3 oz to 100 lb of meat, so for a 10 lb batch of breakfast sausage you would use .3 of an oz or 8.5 grams and that is the upper level.
Anytime you are adding exta ingredients to a prepackaged seasoning mix I would suggest starting out low and then playing around with it until you have reached the desired result!
Hope that helps!
