Whoa. All by itself, this lobster roll is good reason to order some Kewpie. The secret ingredient makes the lobster explode with flavor. I took a sourdough bun, lightly toasted and buttered it, then spooned on some good lobster which had been lightly dressed in butter then mixed with Kewpie mayo and a few chopped bits of green onion (because I didn’t have celery). Umami perfection. Be sure you are sitting down when you eat it.
