Shortbread, Now With Buckwheat

For todays (well, not todays but you know what I mean) micro-recipe, I did a 50% sub of buckwheat flour for normal flour, and a baseline of 1/2 tbsp powdered sugar. So, roughly 1/2 tbsp powdered sugar, 1 tbsp butter, 1 tbsp flour, 1 tbsp buckwheat flour. The dough was a lot firmer and required far more stirring to get the ingredients to come together.

The finished cookies also tasted like buckwheat, obviously. I'm not sure this was a good thing. Another thing I experimented with in this batch was cooling time - I split the single-serving into two biscuits. I at one after 30 minutes cooling time, and ate the second after about 2.5 hours of cooling time. The 2.5 hour cooling time was far superior, as after 30 minutes the biscuit still had quite a bit of heat and chewiness (not something one looks for in an ideal shortbread). The 2.5 hour one was not quite that perfect combination of flakiness and dryness I expect, but it was much closer. I think my baking time/temperature might need some adjustment.
