Whenever we couchsurf we try to bring a small thank you gift to our host(s). If they're really lucky though, we'll cook! And by “we” I mean Auston, but I make a great sous chef.
Our hosts in Prague allowed us to take over their kitchen for a night to do just that. We were excited to have a night in to make tapas and sangria since we often do not have the chance to cook. Depending on the hostel we stay in, there may or may not be a kitchen to prepare a real meal. It was also an excellent opportunity for Auston to attempt a Spanish tortilla which he's been wanting to do ever since we over-consumed them Madrid.
*There were some other dishes I forgot to take a picture of, but when food's in my face the camera's in it's case.
