For the first test, I coated both sides of the corn tortilla with peanut oil and nestled it between two taco holders.
In a preheated Air Fryer at 390, I put it in and after 2 minutes checked it.
And the tortilla was disintegrated.
For the next test, just the tortilla with only the oil remaining in the bottom.
It puffed up.
But it was somewhat crispy.
So I tried three ...
And they need to be pre-softened in order to prevent them from immediately splitting (which happened with two that were discarded).
The Air Fryer had cooled down, but proceeded ..,
This is after 2 or 3 minutes.
Even though the middle one puffed up, it did deflate.
Totally useable.
And the tacos :
Legitimately a far better process than filling a pan full of oil and trying to fry them.
Another new discovery: a 1/4 cup of dried black beans boiled for slightly over an hour, was the perfect amount for 3 tacos.
