Preparation

• Preheat the oven to 350 degrees.
• In a small bowl, whisk together the flour, ground mustard and chili powder. Set aside.
• Pat the drained pimentos dry with paper towels, and mince half, leaving the other half coarsely diced. Toss the pimentos in the flour mixture until lightly coated. Set aside.
• Use an electric or stand mixer to beat together the cheese, butter and salt on medium speed until combined. Slowly add the flour-pimento mixture and continue to beat on medium speed, adding water 1 tablespoon at a time until the dough just comes together, but does not become sticky.
• Turn the dough out onto a floured work surface and roll it out as thin as possible, about 1/8-inch thick. Use a sharp knife or pizza cutter to score the crackers into 2-by-2-inch squares and place them on parchment-lined baking sheet with a little space between each. Pierce each cracker with a fork.
• Bake 16 to 19 minutes, or until just brown around the edges. Let cool on a rack. Crackers will keep in an airtight container up to 1 week.
