Step 1

In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and Stilton together for 1 minute, until smooth. With the mixer on low, add the flour, salt, and pepper and continue beating for about 1 minute until the dough is in large crumbles. Add 1 tablespoon of cold water and mix until the dough comes together

Step 3

Dump the dough onto a floured board and roll it into a 12-inch-long log. Brush the log completely with the egg wash. Spread the walnuts on a cutting board and roll the log back and forth in the walnuts, pressing lightly, to distribute them evenly on the log. Wrap in plastic and refrigerate for at least 30 minutes or for up to 4 days.

Step 17

Meanwhile, preheat the oven to 350 degrees and line a sheet pan with parchment paper.

Step 29

Cut the log into 3/8-inch-thick slices with a small sharp knife and arrange the crackers on the sheet pan. Bake for 22 minutes, until very lightly browned, rotating the pan once during baking. Cool on the pan and serve at room temperature.
