Verdict: Mixed. Taste is good (nutty, rich, faintly spicy, just barely & lightly sweet). Texture is wrong. I had to beat in more shortening to get a workable dough, which may have toughened the proteins in the flour. And I overbaked. The result is more like a small lump of (tasty!) pie pastry rather than the tender, shattering melt-away bite that a polvorone should be. Something about the word 'chrysalines' really captures that feeling, by the way.
Chalk it up to rookie cookie baking. Next time I'm going to make them with a friend in her kitchen, where there's a food processor. We can do bourbon balls, too. They come together in a flash without all the hand chopping, crushing, & sifting.
I'm exchanging them without apology with our neighbors, who always offer a full-out cookie array. If pressed, I'm calling them "snow kringles" <g>.
Happy solstice to all!
