After watching Enrique Olvera make 800-day mole at Pujol on Chef's Table, I was inspired to serve a dish that required a very long period of time to prepare, which I think presents an additional degree of "wow" factor normally associated with restaurant dining. I asked around online and was pointed to tofu misozuke, which is a very unusual "fermented" tofu preparation. Essentially, a block of tofu is cured in a miso mixture for many weeks until it softens considerably to a spreadable cheese-like texture, and picks up a nice flavor from the cure. The folks at Rau Om have kindly published a recipe online distilled from 18th-century manuscripts and other less accessible sources. I added red pepper flakes to my curing mixture to try and impart some extra flavor, and served it on a small cheese board with crackers and some Maldon salt for guests to serve themselves; it makes for a fun play on crackers and cheese to start the meal.
I've served this twice; the first aged a month and a half, and the second aged just under three months. I found there's a magical inflection point somewhere in between those two times; after a month and a half the tofu can be spread and has a pleasant subtle flavor, but the three-month tofu takes on a much, much creamier texture and deeper flavor. I recommend aging at least two months, but in fact you may be able to go for much longer periods without any significant food safety risks. Make sure to keep the container very dry, change the paper towels often, and use your sight, smell, and good judgement when evaluating food safety!
