Ratte Grenaille Potatoes



Airflown fresh La Ratte du Touquet Fine de Ratte (Ratte Grenaille) Potatoes from France

The ratte is a variety of potato native to Lyon. Particularly appreciated by gourmets and cooked by several great chefs. Oblong shape with a firm flesh, known for its thin skin and chestnut flavor. There are several ways to enjoy them! They can be cooked with water, in a pan, steamed, baked or even in a microwave!

In 1986, Joel Robuchon created a ratte-based puree recipe, which allowed the Ratte du Touqet to establish its reputation and make its way on the greatest tables. Recreate this at home!
