It is a bit difficult to make out in the photo since those two splotches on the chashu blur into the brown color of the broth, but the fig compote made it a little sweet, while the balsamic vinegar made it a little tangy.
So this was the crab ramen from Tsuta that I was mentioning last time. The broth was nicely savory and aromatic, and the sour cream was a nice touch, making it better than Hototogisu's version. But I still wouldn't get this next time I'm here; I'd rather go for one of his other bowls.
Sure, I liked the thick chewy noodles underneath, but still, I'm rather shocked in fact that Tsuta would offer such a thing (and I didn't really care for the onigirazu in the background either).
Tsuta Singapore started doing a tonkotsu broth a week or two ago, and it includes two spicy options. I went for the black pepper-based kurobishio variation above, and it was lovely with that black pepper and garlic aroma, not unlike how a good black pepper crab tastes. They actually offered an option for extra pepper if you wanted it, but this was just the right balance.
