Author Elisabetta Pique is an Argentine journalist and friend of the pope whose book "Francis: Life and Revolution," was previewed Saturday in the Italian weekly Gente.
Pique compiled a collection of recollections from Francis' old friends in Argentina and details of his new life in the Vatican as head of the Roman Catholic Church, Italy's ANSA news service said.
The book said Francis was an adept cook, particularly when it comes to the South American dish paella. He starts his day with another regional delicacy, the caffeine-rich "mate," when he gets up at 4:15 in the morning.
At 5 p.m., he likes to recharge with a cappuccino from a machine at the Vatican's St. Martha's House.
