I devised a way to get a pretty good distribution of 3% lard into the dough, but the process, from set-up to clean-up, adds 10 minutes. On the other hand, I seem to get just as good a rise with 3% oil, incorporated as follows: Wait until 85% of the flour is wet, and then add the oil 1% at a time. The oil process takes less time, gives a little more open crumb, is cheaper, and is healthier.
