Sous Vide Raspberry & Rhubarb Cake

Sous Vide Raspberry & Rhubarb Cake

The International Association of Culinary Professionals’ (IACP) annual conference took place this past Friday evening March 27th, 2015 in the Grand Ballroom of the Marriott Renaissance Downtown Hotel, Washington DC.   This year the opening reception featured a parade of cakes as special tribute to renowned chef Jacques Pepin who turns 80 years young this year.  Guests of this elaborate by-invitation event were treated to a grand display of 80 cakes created and donated by members of the IACP family, and chef Pepin’s friends, as well as various chefs representing several food companies throughout the country.
