Cheddar Cayenne Coins

Cheddar Cayenne Coins
6 oz. all-purpose flour
3 oz. finely shredded sharp Cheddar
1 Tbs salt
1/8 - 1/4 tsp. cayenne
4 oz. unsalted butter, cut into cubes, chilled
1 large egg yolk
2 Tbs water
1.5 oz. finely chopped walnuts


Combine flour, cheese, salt, and cayenne in a food processor. Process until just blended. Add the butter pieces and pulse until the dough resembles coarse crumbs. Stir the yolk and water together with a fork and drizzle over the mixture. Pulse until the dough begins to form small moist crumbs. Add the chopped nuts and pulse briefly until the crumbs begin to come together.
Pile the moist crumbs on an un-floured surface. With the heel of your hand, push and smear the crumbs until they start to come together in a cohesive dough. Shape into a 14" long log that's 1.25 inches in diameter. Wrap in plastic and refrigerate until firm, about 4 hours, or up to two days.
Heat oven to 375 degrees. Line two large baking sheets with parchment. Using a thin, sharp knife, cut the log into scant 1/4 inch slices. Arrange about 1/2 inch apart on the prepared baking sheets. Bake until medium to deep golden around the edges, 15 to 20 minutes, rotating the sheets as needed for even baking. Cool on a rack. When completely cook, store in an airtight container.


Bench Notes: I have no idea why I got this from, but, thanks to Google, I now know. Apparently from Fine Cooking. I've been making these since 2008 and really love the flavor and texture of these little crackers, You can also use a mix of half Parmesan and half Cheddar, but I prefer the straight up Cheddar. Mine are never coins, they end up squares, but they still taste good. They can be a bit salty, so I often cut back on the salt.
