You don’t need wet hands to crack an egg — it just makes it easier to get the fragment(s) out. They move away from your dry finger when you try to get them out; they move less if your finger is wet.

Even with the flat plate and pull technique, I still get a fragment maybe once every one or two dozen eggs. Much better than edge-of-bowl cracking, but, still, sometimes there’s a fragment to deal with.

i’ll go re-read my comment and edit if that seems necessary…
