For the cleanest spiral, keep both doughs similar in softness before stacking; if one is firmer, let it sit a few minutes at room temperature. Grinding freeze-dried strawberries to a fine powder in a blender yields the brightest flavor without excess moisture, and you can sift out seeds for a smoother dough. If the log becomes sticky while slicing, re-chill for 10 minutes. To prevent flat sides, roll the wrapped log on the counter a few times after slicing the first few cookies. Flavor swaps like raspberry or cocoa work well—replace strawberry powder with 20 g cocoa and add 10 g more sugar. Baked cookies keep in an airtight container for 5 days, or freeze the dough log up to 2 months.
