This recipe was really tasty! We used medium-sized shrimp and found 1.5 pounds barely fed 4 adults! If serving TEN (really?) you would need at least 2.5-3# of the same sized shrimp. Perhaps using smaller shrimp is different. We used fresh lime juice instead of lemon juice as the lemons this week were wickedly expensive and not at all ripe. We used a whole grain sour dough bread instead of gummy white "Texas Toast". Delicious! When making next, I would again use medium-sized shrimp, but more, and would substitute at least 1/2 the lemon juice for a dry white wine. This is most certainly a "keeper"!
