Well one thing I can sum up from this video via Japan Probe, is that the opinion is probably a very different taste. The reporter kept on making these oohs and ahhs.. so while she didn’t say Oiishi, it would probably be a unique salty sweet tasting dish. I have seen Japanese love Mayonnaise, but first time I even saw it as a soup base for Ramen.. so yes to those who have tried it..
But for people who would probably say eww.. Japanese mayonnaise is not Hellmann’s version.. which is pretty heavy. While I am not a fan of eatting much mayonnaise.. would maybe like to try this one out.
