The dish isn’t available until Valentine’s Day, but RocketNews24 sampled an early version and says two obvious methods exist for ingesting the chocolate:
The first is to simply grab pieces of chocolate with your chopsticks and eat them like you would any other ramen toppings. However, while the chocolate chunks are perfectly tasty, eating them like that doesn’t really give you any different of an experience from eating chocolate in the ordinary, non-ramen manner.
Instead, we recommend stirring the chocolate and giving it some time to melt into the broth. This gives the broth a pleasant sweetness as you first take a sip, but still leaves the aftertaste sharp and clean, with no unwanted lingering saturation of your taste buds.
Eating this ramen will ipso facto make Valentine’s bittersweet, but, on the other hand, one could argue it’s also got the ingredients for a cheap date: two bowls of ramen for less than $15, noodles to do the Lady and the Tramp thing with, and no need to splurge on dessert with all that broth-y chocolate at the end to slurp up.
