I added sage, gram masala, coriander, cumin, the batch I made last week tasted a little light on the spices. I also added garlic powder to the spices that go on the beef.
I added two bags of dark chocolate chips. I think it probably would have been fine with just one bag. They seem a little...dry is the wrong word, because they are not dry. Just a little chocolate-heavy. I think I should have doubled the recipe and then done two bags of chips.
