In a large bowl, add the flour, lard, and salt. Add in the cooled syrup, 1 tablespoon at a time, and mix with a fork until a smooth dough begins to form.
Start kneading with your hands for 5-8 min until the dough is soft and smooth. Place back in the bowl, cover, and let it rest for 20 minutes at room temperature.
