Close to the ground with visual refrences, I "step on the centerline". Airborne, in the clouds I initially respond with airlerons, shortly followed by "stepping on the low yoke side". The above techniques are pretty idiot proof.
Rudder is an absolute necessity in an engine out. i believe a BA 747 almost clipped a hilltop in Oakland California, because the pilot controlled with all aileron and no rudder. The aircraft couldn't climb with all that aileron.
