Today, we offer you the recipe for the most famous potato gratin on the planet: gratin dauphinois. And be careful, here we don't joke with tradition, so this is the real recipe that we share with you, the one directly passed down by our grandmother from her French cookbook (and yes, Petitchef is a French chef!). The best accompaniment for your meats and fish but also a dish that we will enjoy eating as is :-)
