Whiz the dry ingredients, plus the rosemary and cheese together in a food processor fitted with a steel-blade attachment. Add the goat butter, and regular butter and pulse until the mixture becomes sandy. Carefully drizzle the egg into the mixture while pulsing just until the dough turns on itself. Remove dough from processor, shape into a log, wrap with plastic and freeze for 30 minutes, or until firm.
Preheat the oven to 400 degrees F and line a cookie sheet with parchment paper. Cut the log into ¼ inch slices and set on the prepared sheet, about ½ inch apart. Press a couple of slivered almonds into each cookie and lightly sprinkle the tops with sea salt. Bake for 12-14 minutes or until the cookies are lightly golden brown.
Let cool on the sheet for 5 minutes, then transfer to a cooling rack to cool completely.
Store in an airtight container.
