Una franciacortina in cucina is a wonderful food blog by franciacortina Arianna Vianelli, who also works with the Franciacorta consortium as its in-house caterer.
Her blog is devoted primarily to Franciacorta’s rich culinary traditions and she posts wonderful photos and recipes (in Italian) on a weekly basis.
Check out her awesome post on spaghetti with cured sardine from Lake Iseo, a supreme classic of franciacortina gastronomy and a traditional pairing for Franciacorta (wine).
Don’t be surprised if you happen to find a translation of her recipes here from time to time (I took that photo of her spaghetti with sardine dish back in November 2014).
Even if you don’t speak Italian, a little bit of cookery skill and Google Translate make Arianna’s blog highly accessible and easy to follow. The photos alone are worth the price of admission.
