I’m sorry, I keep promising you blood orange shortbread, and I keep not delivering, but in my defense, I forgot that I was making a double batch, and I only have two wire racks, so I had to wait 24 hrs for one batch to dry, before I could candy the other batch (which is drying now). Shortbread tomorrow, I’m pretty sure. 
There’s a lot of variation in the blood orange colors, I have to say. Only a few were really bloody….
