I tried the pecan pie recipe that I posted before again with some small changes. This time it was all walnut instead of a walnut-pecan combination, and I added a handful each carob chips and shredded coconut.
I liked the carob-coconut-walnut flavor combination quite a bit. It was a bit richer than the other pie, and had deeper flavor.
I also decided to try using cornmeal instead of flour to thicken the filling. I found the result to be a bit gummy on the first day but pretty good on the second. I may go back to flour in future pies or try a combination of the two.
