Digging soap out from the puck seems a strange thing to suggest - mind you I've not used OSP soaps, but, if it's a hard soap, it shouldn't be necessary. My formula for face-lathering hard soaps is as follows:
1. Soak brush (if natural hair) in warm-to-mildly-hot water while face prepping
2. At the same time, wet or soak the puck with warm water
3. Once face is prepped and wet, give brush a quick, light squeeze and one flick to remove excess water
4. Pour water off the soap
5. Load brush from soap, using swirling motions and moderate pressure. IMO, the tips of the brush should partially spread, but don't force the brush to splay the knot.
6. A couple of times during the loading process, I stop swirling and gently 'pump' the brush onto the soap, this releases any excess water trapped in the base of the knot, which can cause lather in the brush to turn wet and bubbly between passes
7. Continue loading until the end third of the knot is filled with lather, and there is a continuous covering across the width of the knot at the tips. You should find yourself craping lather from the top of the puck where it meets the walls of the container and placing that on the brush
8. Lather the face for at least 30 seconds, checking lather consistency
9. If the lather is too dry, lightly dip the very tip (literally the end millimetre or two) of the brush briefly in the basin of water, and reapply. Repeat as necessary until a smooth, lubricating, dense but not sticky lather with a semi-gloss/pearlescent finish is generated.
