Organic Masa from Bob's Red Mill The ideal pantry essential for fans of Mexican and Latin American cuisine is harina flour. It is created with cooked, limewater-treated, and finely ground organic maize that has been certified as organic. Perfect for preparing homemade pupusas, sopes, and corn tortillas. Our masa harina produces outstanding corn tortillas, much like fresh masa, when combined with water and a little salt to form a smooth, bouncy dough. After that, divide the dough into two-inch balls and press them before cooking them on a hot griddle. Add your preferred fillings and sauces on top, and don't forget the lime wedges!
