This is from "Cuisines of Portugese Authors," in which the author recounts dishes from her travels through Portugal and its former colonies. She said it is a popular salad on Sao Vincente. If desired, add lobster or shrimp to make a light, complete meal. Recommends serving it with white Dao wine. I haven't tried it yet. I assume she means dried dates. The filling needs to chill at least two hours before the shells are stuffed. I'm not sure how we're supposed to keep them from browning during that time period.
