Though my family would be perfectly happy with the status quo, every year, to satisfy my own creative side, I always try to make one "something different" flavor, in addition to our traditional prune and apricot. There are no poppy seed ("mohn") hamantaschen in our house because if Avram's immune system even gets a whiff of them, he won't NEED a Purim costume ... his distorted features will easily qualify.
I've attempted raspberry (too runny).
I toyed with chocolate and chocolate nut (a combination I really wanted to make work, but nobody seemed to enjoy).
This year I chose lemon/lime.
Early indications seem to show that although they lack color contrast, the tangy flavor is a hit. In fact, there may be none left by Rosh Chodesh Adar II unless I rush them into the freezer PRONTO.
What did I miss most this year?
The fact that all the little ones are grown, or nearly so.
No more eager little tongues darting out to test if the filling had cooled down enough. (Though there were still plenty of fingers swiping the goods the minute my back was turned....)
Ah, but it seems like yesterday ......
