Let the host know in your request what you’ve already tried and be honest about wanting to try something new and different. You will also be able to communicate with the host directly after booking so that will also be an opportunity to clarify any details.

But keep in mind that sometimes the same dish you ate before like miso soup might be completed different at the next home because of regional differences in the miso paste being used or simply the ingredients being used depending on the host. Just be sure to ask.
