This recipe is very old. Marie-Therese’s aunt worked as a maid for a very rich family of textile industrialists, called Motte. This family lived in Mouveaux in the north of France, not far from Tourcoing. This region is also called French Flanders, because it was part of Flanders in the past. One of the family members was even a mayor of Roubaix in the twentieth century. This family is still one of the richest families in the north of France. It made its fortune thanks to the textile industry.Marie-Therese’s aunt was a very good friend of the house’s old cook, Marie Delanoye, who died in the 1940s. Her aunt, Zoë Lambert, never forgot the old recipe she got from that cook.
