This bread needs to be eaten fresh as it will turn dryish and harden if left out uncovered for sometime.
Instead of 310 ml of hot water you may use 1 cup (240ml) of water, 1/4 cup of olive oil and 2 tablespoons of milk which I believe will yield a much softer bread than I did (if you will keep the bread for a while you need it much softer). However I haven't tried it but believe the results will be good as with any bread that has fat (oil in this case) in it.
