Boil frozen edamame in salted water for 5 minutes(or according to package directions). Drain and add to food processor.
Add tahini, lemon juice, capers, garlic, parsley, spices, and salt. Turn on processor and slowly stream in olive oil. Continue processing until smooth(it will probably be pasty at this point). While still processing, slowly stream in water until desired consistency. Scrape down sides as needed.
Taste for salt and add more if desired. Refrigerate. Flavors will blend and develop more if refrigerated for at least 2 hours.
