Mix together the bulgur, oatmeal, farina, flour, salt, mint, basil, cayenne (if using), and black pepper; add the hot water a little at a time, stirring to create a workable dough. Knead gently. If mixture is too dry, add a little more hot water.
Take a ball of the dough the size of a golf ball. Make an indentation in the center with your thumb and keep opening and shaping with your index and middle finger. Press down in center and sides, rotating until you get a thin shell.
To make the shell as thin as possible, line a small plate with plastic wrap, take a golf ball sized piece of the ‘dough’, flatten it into a circle with your hand, then gently lift it off the plastic – while trying not to break it. Keep a small bowl of water to dip your hands into for this process. The water helps ‘glue’ the outer shell together. Place one tablespoon or more of filling in the center, gently encase the filling with the outershell. Finally, smooth the surface with wet fingers, making sure the kufteh is flat on the bottom and slightly rounded on the top.
Place shaped kutfehs on a waxed paper-lined tray or plate, and refrigerate for 20 minutes.
