I bought some plain gelatin, which is just a protein, so it is safe for the crabs. I'm going to use hibiscus tea instead of water and make a hibiscus jello, sweetened with a bit of honey.

I can't wait to see how it turns out! If it's successful and well-taken by the crabs, it'll be a new product for my food store.
