Preserving Sea Urchins
These are extremely delicate so you must be careful when cleaning. If you have time (and are somewhere upwind from them) you can let them sit out in the sun for a few days and then brush off the spines. After this you flip them over and with a dental pick or some other similar instrument pick out tissue that will be in middle. If odor will be a problem you can dip them in bleach and rub off the spines (wear some gloves). After the spines are removed take a dental pick to the bottom center of the urchin and remove tissue. Dip in the bleach again then rinse well in fresh water and dry.
