My Dad is very fond of a creamy sesame dressing found in Japanese restaurant near him and has asked me if I can come up with something close to it. I tasted it, tasted it, and tasted it and came to a conclusion that it's a commercial based salad dressing with raw eggs, very sharp vinegar taste reminiscent of kewpie mayonnaise taste and something else I could not pinpoint. That salad dressing is good, but when you taste it by itself, I realize there were lots of stablizers, preservatives, and chemical taste that I did not like. But still, I had to come up with something for Dad because he was paying $5 for a cup of this dressing and he was going through it quickly. This is my rendition and I think much tastier one that I am proud of. You can easily grind roasted sesame seeds in coffee grinder for 1 second or you can mortar and pestle. It should only be partially ground
