What kind of crabs? Blue crabs make excellent gumbo & stuffed crab. King crabs are tasty swimming in butter. Dungeness crab, hmmm, don't know what it's called but it's chunks of crab in a thick cream sauce over pasta. Then there is cangrejo del mar diablo. Probably hard to find those spices in Canada.
Argue for your limitations and they are yours forever.
I'll never forget the time I was excitedly telling my coworker that my husband had crabs. We worked in a Christian preschool and she was in her 60s and me in my 20s, and we were surrounded by three-year olds at that moment, and she just gave me this look and started laughing. I said something like, "What did I say? My husband went to the beach and picked up some tiny little crabs and has them in an aquarium down in our basement." She just kept laughing. I asked her what else "crabs" meant. She told me I should ask my husband. And that's how I found out that crabs aren't just creatures that live on the beach.
