Living on a boat means to have (almost) everything within a small place similar to an appartement or house on land. Unless you go for diner each and every day a kitchen, which is called pantry on a boat, is necessary as well.
This gives a little Impression how our pantry and cooking looks like. Since I was surprised that here was a holyday yesterday I checked what I can cook based on the ingredients we have on board.
I found potatoes, package of pizza-tomatoes, eggs, chorizo, paprika and some spicery. Exactly what you need for a spanish potato gratin.
