This was a great idea, but the execution was a little iffy for me. My first problem may have been guessing at the temp; since none was listed, I went with 350, but it took more like 15-16 minutes to get any browning at all on the bottoms. The lavender flavor is great in shortbread, though. Also, the first dozen I baked were lumpy mountains, due to my using the "drop by teasponful" method. The second dozen I flattened with the back of a spoon and liked a little better.
Overall, the lavender flavor is a great idea for shortbread. I will try again, probably with the more traditional chill-the-dough-roll-and-cut shortbread method. I'm thinking a rose water glaze would be fab, too.
Test Kitchen Response: Thanks so much for your review and for pointing out that the baking temp was missing! We've fixed that...it's 375 degrees. Our favorite way to do these cookies in the test kitchen is with one of those baby ice cream scoops so you get even mounds (instead of lumpy). Love your rose water glaze idea!
