As I mentioned in another thread, I'm planning to have some people over for tacos. I want to make wheat tortillas. I've tested and verified that the tortillas can be rolled out and kept in plastic in the fridge over night, then cooked the day after. Saves lots of time.
The problem now is that these tortillas seem to go hard very quickly. When testing today, I warmed a ceramic bowl, then stored the tortillas in a kitchen towel in the bowl. Tortillas stay warm-ish and soft in the towel - so far, so good. However, when grabbing one and filling it, it starts to get stiff before I get to start eating it. What can I do to improve on the situation? Keep them hotter? More fat?
For completeness, here's the recipe I'm using:
5 tbsp lard
2 2/3 cup flour
1/2 tsp salt
3/4 cup warm water
