This is a quiz question that I haven't found the answer to. 'Which term, coined in the 70's, describes food that does not have rich sauces?'. I thought it may be Nouvelle Cuisine, but could it be simpler still.....and wasn't NC more 80's?
NC rethought classic French by simplfying and lightening. Ch F Point originated the idea "Les Pyramides" Viennes, Fr. Use of cream, butter and flour were minimized. Continues to revolutionize cooking.
Another, Cuisine Minceur for rich dieters was the brain child of Ch M Guerard
