What’s for Dessert at the White House

In honor of President’s Day I thought we needed a little education on how things work in the white house kitchen.  Per Wikipedia:
 

The White House Executive Pastry Chef is responsible for the planning, managing and preparing of all desserts and pastries served at the White House, the official residence of the President of the United States. This includes State Dinners, official dinners, and private entertaining by the First Family.
The Executive Pastry Chef works separate from the White House Executive Chef and reports directly to the Chief Usher. He works in coordination with these two, as well as the White House Social Secretary, and the First Lady for all events and dinners. The Executive Pastry Chef serves at the First Lady’s pleasure and is appointed, or reappointed, by each administration.
The current White House Executive Pastry Chef is William Yosses.
