How to Make It
In a large bowl, whisk the flour, cornmeal, brown sugar, baking powder and salt. Using a pastry blender or 2 knives, cut in the butter until the mixture resembles coarse meal. Add the evaporated milk and stir until a dough forms. Turn the dough out onto a lightly floured work surface and knead just until smooth, about 1 minute. Cover with plastic wrap and let stand at room temperature for 15 minutes.
On a lightly floured work surface, roll the dough into a thick rope. Cut the dough into 24 pieces and roll each piece into a 9-inch rope. Bring both ends together and twist each rope tightly.
In a large saucepan, heat the oil to 350°. Fry the twists, about 8 at a time, until golden all over, 2 to 3 minutes. Drain on paper towels and serve hot.
