Were the ice cream bowls x-grain, so rim to center is the proper cut direction? End grain is opposite, ID to OD. A bowl gouge can be used - a long wing grind is needed, because it sweeps the sides away from the nose, helping to keep the amount of edge cutting smaller. It is easy to get too much edge into the cut and get a catch. The bevel angle is not that important - 40-60 deg can work.
I generally start with a 1/2” spindle gouge with a fingernail grind. It is easier to control the cut size. Depending on the OD and depth, and the tool rest (how far into the shape it can reach), the spindle gouge may begin to chatter. A bowl gouge, having a fuller flute, can hang further off the tool rest vs a SG.
Richard Raffan, and I think Tomislav, both show endgrain hollowing with a SG. They move the tool vertically. I do the same but more horizontally, because I can see the tool edge. I can’t see it with the vertical movement, and never got comfortable with it. They have utube vids showing it.
There limits with either tool getting into the lower corner. Typically that corner will need a scraper, and the smaller the corner radius the more a scraper is required. The cupped carbide tools, like the Hunter series, are good at getting into that corner, and coming up the wall.
