Actually my favorite tofu is the tofu in mapo doufu. But that's cheating. When it comes to pure tofu, this is my new favorite: spicy braised tofu from Bon Appetit, aka dubu jorim.
Shown here with fried coconut rice (fried because the coconut rice I'd made was mushy so I added some cornstarch and fried it real good and crisp) and sigumchi namul.
I changed one thing from the Bon Appetit recipe: I coated the tofu pieces in cornstarch and gochugaru. Not sure if this is the reason but my tofu pieces had a nice crisp which stayed even when coating in the spicy sauce.
