I had leftover lekvar and I mulled over all these creative options for using it up in a dessert. When I presented these options to my husband, along with the option of a simple prune danish, my husband voted for the danish.
The filling for this danish can be straight-up lekvar spooned out from the jar, but I decided to make it a little more interesting. Walnuts, mini mocha chips and an orange-vanilla glaze add extra texture and flavor.
As far as the dough is concerned, I use a few tricks to make and bake the dough extra quickly: (1) putting the dough in a warm oven to push it to rise faster; (2) folding the dough at intervals to strengthen it instead of kneading; and (3) putting the shaped dough in the oven after a very short (15 minute) rising period. With these tricks, the recipe will take about 1 3/4 hours from assembling your ingredients to pulling the danish out of the oven. If you take things a little slower or allow for a slightly longer rising time, it will take closer to 2 hours from assembling your ingredients to pulling the finished danish from the oven.
If you double the dough, you can make two small challahs plus the danish.
