Pita bread can dry out very quickly after its package has been opened. The thin texture and airy quality of pita bread makes it a target for moisture evaporation. Pita bread tastes best slightly warmed and richly moist. If pita bread has dried out too much, any filling will fall out of the cracks that quickly will develop. Softening pita bread only takes a couple of quick tricks.
Place the dried out pita bread in a 1 litre (1 quart) plastic bag. Also place a thick slice of moist bread into the bag. Leave the bread in the bag overnight, and the pita bread will absorb the moisture from the moist bread slice. You may need to place two pieces of bread in with the pita bread, depending on how dry the pita bread is.
Moisten a clean kitchen towel under the tap. Allow the towel to get moist but not soggy. Run the towel under warm water and wring out the excess water so that the towel is consistently damp.
Wrap the dry pita bread in the kitchen towel and place on a microwave-safe dish. Place the dish in the microwave and heat for about ten seconds. Alternatively, place the wrapped pita bread in the oven and heat at 93.3 degrees C (200 degrees F) for about ten minutes. This technique is best if you are going to eat or serve the pita bread right away.
Keep pita bread stored in an airtight container or plastic bag to keep it from drying out.
