I have always made my own venison mincemeat pies but there is a dry package of mincemeat 'spices' or condiments' that I have used.
About 2 cups of lean ground venison, 1 cup of finely diced apples, 2 cloves, 2/3 cup of raisins, 1 tsp ground cinnamon, 1 tsp salt, 1/4 cup of sugar or maple syrup - if you use syrup instead of sugar use only 1/2 cup of apples and use more raisins, or it will be too wet.
