Rarely seen Maggi seasoning on sale.
I'm going to try to blend the sriracha mayonnaise mentioned by @shkippy
I remember an amazing sauce made by Dan Hong that he called "comeback sauce". Then I found the recipe and was surprised how simple it is: Kewpie mayo, maggi liquid seasoning & sriracha. But a word of warning, once made that stuff is highly addictive.
