In a medium saucepan, bring salted water to a boil. Add rice, reduce heat, cover and simmer for 20 minutes. While rice is simmering, combine shrimp, ginger, cayenne pepper, garlic, sesame seeds and black pepper in a large plastic food storage bag. Allow to marinate in the refrigerator.
Place raisins, sugar, butter, eggs, milk, and vanilla in a large heavy-bottomed saucepan. Cook over medium heat, stirring frequently until mixture is hot, slightly thickened, and just beginning to bubble, about 4 to 5 minutes. Cool slightly, uncovered, in the refrigerator, while continuing with recipe.
Blend the pear, white wine, garlic, Dijon mustard, white balsamic vinegar, black pepper, and sea salt in a blender until well combined; drizzle the olive oil into the mixture in a thin, steady stream while continuing to blend. Blend a few seconds longer until the salad dressing is thick and creamy.
