My sister saw a can of spotted dick at the supermarket not long ago. She left her cart in the aisle and ran out to call me. She was laughing so hard she almost wet herself. Sis had no idea what it was. I had to explain to her that it was pudding and the “spots” were raisins.
LOL!! I believe I first heard about it from the Monty Python shows. Then I saw it being offered from a catalog selling British goods. I cracked up because up until then, I had no idea what it was either.
