We tried both tonight for comparison.
To start with, the soup version definitely appealed more to us for a rich duck broth ramen. Indeed it was so the broth got a little jelak after a while and when it turned cold.
The dry ramen, on the other hand, was just a little dry although it smelled terrific. But as soon as we wet it a little with the broth, it tasted wonderful. Interestingly, the dry ramen seemed to get more flavourful with each mouthful, with the chopped onions, cashew nuts and black pepper.
Overall, both were tasty although the dry version prevailed once the soup lost its heat. Nevertheless, the chopped onions might not go down well with those who do not fancy its distinct taste. For the others, it was just great.
