i've seen them both ways htc. most shops had the dried, but a few of the bird specialty places had them fresh. i guess they give them to their own birds. i keep mine refrigerated in a paper bag, like alot of other fresh veggies, because they will spoil. i wonder if it that's the right way to keep them, or should they be kept more like potatoes, or airtight.
Marinate the shrimp in the sesame oil and lemon juice for 30 minutes to 1 hour. While the shrimp is marinating, combine the remaining ingredients into a sauce and heat in a pan for 10 minutes over medium heat. Skewer the shrimp with vegetables and/or fruits of your choice, and grill them, using the sauce for basting/dipping.
