This recipe also works well with Cajun Style Blackening Seasoning in place of Coastal Bay. Or try it with your favorite BBQ blend.
Combine flour, cheese, salt and seasoning in a food processor and pulse until just combined. Using a cheese grater, shred stick of cold butter into flour mixture (or add butter in small pieces). Pulse until mixture resembles coarse crumbs. Add yolk and water and pulse until mixture resembles moist crumbs. Turn loose dough out onto floured work surface and, using the heel of your hand, gently push and smear crumbs away from you until a cohesive dough starts to form. Fold the dough onto itself a couple of times, smear it again, and then shape into a 1¼-inch diameter log. Wrap in plastic and refrigerate until firm, at least 2 hours or up to overnight. Preheat oven to 375 degrees. Cut log into coins 1/8- to 1/4-inch thick and place on parchment-lined baking sheets about ½ inch apart. Bake 10 to 15 min. until golden around the edges. Remove and cool on baking racks. Serve once completely cool. Store in an airtight container.
These make a great party snack. Or serve as a topping to a green salad or add to a cheese plate.
