For this particular sausage, I used cow intestines because they come in different shapes. This was pre-cleaned to remove the fats surrounding it, washed thoroughly, and mixed with salt before preserving it in the freezer. To use, i simply soaked the frozen intestines in water, then rinsed thoroughly. Now, the type of intestine you'll use will be determined by the size of the sausage you want. You can determine that by filling the intestines with water like i am doing right now. The expansion limit will tell you how large or small your sausages will be. Large intestines will give you large sausages and small intestines will give you small sausages.
Fill a piping bag up with the meat mixture then make a hole at the end. pipe the meat into the intestine. With twines, demarcate the sausages and tie up the sausages according to the size you want.
If you don't have intestines available, you can buy the sausage casings sold in the market. it's made from collagen. If you’re using collagen casings, soak them in warm water for about 30 minutes to soften. Then, load the chicken mixture into a sausage stuffing and fill the casings, twisting them every few inches to form links.
If you’re not using casings, simply shape the mixture into sausage-like logs and place them on a baking sheet.
