Step 1

For the buttermilk biscuits: Preheat the oven to 350 degrees F.

Step 2

Pulse 3 cups flour with the baking powder, salt, sugar and baking soda in a food processor. Add the butter and pulse just until the butter is in pieces the size of small peas (might take longer than usual because it is frozen).

Step 3

Remove the mixture to a large bowl and fold in 1 1/2 cups buttermilk with a fork, just until the dry mixture has absorbed the liquid. Do not overmix.

Step 4

Place the remaining 1/2 cup flour on a work surface and dust a rolling pin with it; knead the dough just until it holds together, 2 or 3 turns. Roll out into a square shape, using a pastry scraper or knife to shape. Roll out about 1 inch thick.

Step 5

Cut four equal squares and stack on top of each other. Roll out again, same thickness (about 1 inch).

Step 6

Use pastry scraper or knife to cut into 8 to 12 biscuits, depending on the desired size (Full Belly Deli size or normal human size). (You should be able to see multiple layers in each biscuit.)

Step 7

Place about 1 inch apart on a sheet pan lined with a silicone pad or parchment paper.

Step 8

Brush the top of each biscuit with the remaining 1/4 cup buttermilk and then add a pinch of salt and fresh cracked pepper to the top of each biscuit.

Step 9

Bake for 25 minutes. Set aside.

Step 10

For the chorizo-sausage gravy: Add canola oil to a large stockpot and heat, about 2 minutes.

Step 11

Add Basque chorizo and breakfast sausage to hot oil (be careful not to splash; add meat slowly). Sear meat, stirring, and cook through thoroughly, about 10 minutes.

Step 12

Add flour, garlic powder, onion powder and paprika and cook on medium-low heat to cook out flour flavor, 5 to 7 minutes Gradually add half-and-half and whole milk, continually stirring. Increase heat and bring to a boil slowly to thicken, being careful not to scorch the gravy. Add salt and pepper to taste.

Step 13

For the burrito: Deep-fry hash brown triangles in a saute pan with canola oil for about 2 minutes on medium heat. (If using another style of hash brown, saute in pan with 2 tablespoons of canola oil until crispy, 10 to 15 minutes.)

Step 14

Lightly toast tortillas. Set warm tortillas on cutting boards or a work surface. Add 2 slices Cheddar to each. Slice 1 buttermilk biscuit for each and place on top of cheese. Add crispy hash browns and cover with desired amount of chorizo-sausage gravy.

Step 15

Wrap burritos and grill on a panini press or in a cast-iron pan over medium heat, 1 minute.

Step 16

Slice in half and serve immediately.
