Self-raising.
Listen up, buttercup. This joke is funny because orphans are kids whose parents are dead. "Self-raising" flour is a type of flour that makes bread rise without needing other stuff. It's a play on words because orphans are "self-raising" since they don't have parents to raise them. You probably needed me to spell that out, you dummy.
