This is a hard one. Ready?

Really this is quite an amazing discovery, because cocktail sauce is something I always thought you had to go buy because it had some patented top-secret ingredient to it. Except it turns out that it’s just ketchup and horseradish (or, in this case, wasabi).

What if tonkatsu sauce turned out to be the same way!? Life would never be the same again. There might actually be room on the fridge door!
