I made several adaptations to the original recipe. The first was that although the shortbread is wonderful plain, it is it, indeed, plain. I think a little lemon zest, a splash of vanilla or even both would work deliciously in the dough, and against the raspberry. The suggested baking time is almost half of what I needed to get them solidified and lightly golden in the oven-mine took an hour, in the end, and I do not suggest you take them out before they truly look done. Finally, I knew immediately that raspberry jam could not be spread over a pile of cookie shards, and plopped it into a piping bag with a big tip instead. A zip-lock bag with a
