Tacos are fried in advance but filled just before serving. To prepare the taco shells the large cooked tortillas are folded in half and kept partly open with a perforated spoon while fried in oil until crisp. If preferred or if smaller tortillas are made, small round tacos or taco chips may be fried flat without folding. Serve the tacos in the same way as tostadas.
