This is the origin of such well-known dishes as cod Biscayan style (or "al pilpil"), the “marmitako", the "txangurro", huge red and white tuna, etc. On the other hand, in the mountains we can find the highly acclaimed mushrooms that give any dish its unique aroma and flavour.

Tolosa beans and Gernika peppers are a great example of the quality of Basque products. Progress has been made in the cultivation of plants with respect for the environment and improved care of the land, but there has also been a commitment to improving livestock farming in accordance with ecological principles and respect for animals. All of this has provided Basque gastronomy with high quality products that help to maintain Basque cuisine at a high level.
