TACROS (CROISSANT TACOS)

Steps:

• Combine masa harina and boiling water in the bowl of a stand mixer. Mix until crumbly and set aside to soften for a few minutes. Combine bread flour, gluten, sugar, salt, and yeast in a small bowl. Pour milk into the bowl with the masa; add flour mixture and lard. Mix on low speed with the dough hook until dough is well combined and clears the sides of the bowl, about 2 minutes. Scrape dough down and mix for 5 minutes more to develop the gluten; dough will be very stiff. Transfer dough to a lightly oiled bowl and cover with plastic wrap. Let rise at room temperature, about 1 1/2 hours. Place butter in the same mixing bowl and use the paddle attachment on low speed to break it up. Mix just until smooth. Scrape butter onto a piece of parchment or waxed paper. Form into a 7-inch square. Cover with another piece of parchment and smooth the top with a rolling pin. Re-form the edges of your square if necessary; a little fussing now will save you some trouble later on as you roll out the dough. Place butter square in the refrigerator to chill. Transfer dough onto a floured work surface. Pat it into a square, transfer to a parchment-lined baking sheet, cover with plastic wrap, and refrigerate for 1 to 24 hours. Remove butter square from the refrigerator about 20 minutes before you plan to roll the dough; it needs to be cool and pliable. Transfer dough onto a floured work surface. Roll it into a square a little larger than the butter square. Leaving a 7-inch square platform in the center for the butter, roll each of the 4 corners of dough out into elongated flaps that can wrap around the butter like a present. Place butter square in the center of the dough, fold up the flaps, and pinch together to seal. Roll dough out into a rectangle. Fold in thirds, like a business letter. Wrap in plastic wrap and refrigerate for 30 minutes. Return dough to the work surface; dust with flour if needed. Roll dough out into a longer rectangle; you're going to do a 4-fold, also called the
