The only orange liquor I had was Blue Curaçao so I added one tablespoon as I saw it was turning the filling blue so I used a capful of orange extract. Tasted great. Easy to make. I used a Keebler ready made vanilla pecan pie crust. For the filling, I cut the one cup sugar to half and I think next time I will even use less. The berries were sweet enough without using all that sugar.
