Recipe(tried): Sesame Dressing like Marshall Field's

SESAME DRESSING

1/2 cup corn syrup
3 Tbsp. white distilled vinegar
2 Tbsp. pineapple juice
4 tsp. granulated sugar
1 Tbsp. light brown sugar
1 Tbsp. rice wine vinegar
1 Tbsp. soy sauce
1 tsp. sesame oil
1/4 tsp. ground mustard
1/4 tsp. ground ginger
1/8 tsp. salt
1/8 tsp. paprika
dash garlic powder
dash ground black pepper
1/2 cup vegetable oil
1/2 tsp. sesame seeds

Prepare dressing by combining all dressing ingredients except vegetable oil and sesame seeds in a blender on high speed.

Slowly add oil to mixture (to create an emulsion).

Add sesame seeds and blend for just a couple seconds. Pour into covered container and chill.

This is from Todd Wilbur's Wendy's Mandarin Chicken Salad. It's the closest I've found to Field's.
