Combine the pimento cheese and butter in a mixing bowl and beat with electric mixer until combined.
Add the flour, Aji Mirasol, orange zest, toasted cumin, pepper and sugar and mix until incorporated. Flatten the dough into a disc and wrap securely in plastic. Chill dough for at least 2 hours and up to 2 days.
Preheat oven to 400 degrees.
Unwrap dough and place it on a floured surface. Roll the dough to 1/8" thickness and, using a cookie cutter, cut into desired shape. Re-roll left over dough until its gone.
Place the cookies onto a baking sheet lined with parchment paper. Gently press a pickled jalapeño slice in the center of each biscuit.
Bake for 15 minutes or until golden brown. Cool slightly before transferring to a cooling rack to cool completely.
