The lime flavor comes out very nicely. I would recommend an extra 2-3 minutes baking time, as my first batch turned out a little under done. The second was just perfect. Also, I only used 1/2 cup icing sugar for the glace. Very nice cookie. :)
Although these cookies turned out well in the end, I had a lot of trouble with the dough. I knew when I blended in the dry ingredients that the dough was too dry to form any shape, & it was still the case after an hour's refrigeration. I wound up adding about 1 Tbsp melted butter and a dribble of milk to get the dough pliable enough to work, and I guess this added to the baking time as it took them 16 minutes to bake. The flavor is good - I think I'd like a bit more lime flavor - and I think I would add a green food coloring to the drizzle -- for which I only used 1/3 cup of conf sugar with the lime juice. I think 2/3 would've been an odd consistency.
I too am crazy about lime. These were great, I took them to a baby shower and everyone wanted the recipe. Thanks for sharing.
