Splenda? Seriously? I’ve never seen a recipe actually call for it before. We omitted it completely, a whole cup of any type of sugar/sweetener is way too much in my opinion. I used less sugar as well, maybe 1/3 cup total. Maybe that was why the lime was too strong. Recipe from Epicurious. Makes 4 servings. Directions For dressing: Mix lime juice, sugar, Splenda, soy sauce, garlic, and pepper flakes in a bowl; set aside. Core lettuce and separate leaves; rinse and dry them. Cook shrimp with its marinade in a medium pan or wok over medium-high heat, turning shrimp until opaque, 2 or 3 minutes. To make wraps: Place 3 shrimp inside each lettuce leaf along with 2 or 3 basil leaves, 1 tbsp carrots and a small handful of noodles and roll up. Divide dressing among 4 small dishes for dipping.
