From John Martin Taylor in Gastronomica, Fall 2008, who bases his recipe on a survey of old southern recipes. Also in https://www.washingtonpost.com/recipes/john-martin-taylors-blue-cheese-straws/13436/.
With a processor, this comes together very quickly. I grate the hard cheeses in the processor, but just crumbled the softer Blue. I then rolled the dough between sheets of cling film and cut with a pizza wheel or pastry scraper; both worked well, but the scraper made transferring to the parchment easier.
113 g 8 ounces Blue Cheese
56 g 2 ounces Unsalted Butter, cut into chunks (half stick, 4 TBS)
1/2 tsp Salt, plus more for garnish
1/4 tsp Cayenne pepper, plus more for garnish
145 g 1 cup All Purpose Flour (preferably soft Southern)
1 Egg Yolk (if needed for moisture)
Preheat oven to 375F (or 350F convection).
Line 2 cookie sheets with a Silpat or parchment so straws don't stick.
Crumble or grate cheese in a food processor.
Combine all ingredients except egg in processor with metal blade and process a minute or two until it forms a ball.
If it's too dry, add the Egg Yolk (some recipes use a bit of Milk or Buttermilk).
Divide into two batches.
(Many recipes chill the dough for 30 minutes at this step, try if you've got a hot kitchen)
Roll into 1/8 inch thick slabs about 6-inches wide between sheets of cling film;
I use a rolling pin with thick O-rings on the ends for even thickness.
Garnish with Salt and Cayenne, roll once lightly to press in.
Cut into 1/2 inch wide strips, each 6 inch long.
Lay out on cookie sheet, with strips not touching.
Bake 20-25 minutes until just lightly brown.
Cool on rack.
