Mary K. Sim, 92

Mary K. Sim, an accomplished cook who proved a Julia Child recipe didn't work and received an acknowledgment from the TV chef, died of heart failure Feb. 12 at her home in Columbia. She was 92.

Mary Kinnard was born and raised in Cashmere, Wash. After graduating from high school in 1932, she was a pre-med student at the University of Minnesota.


In 1934, she married John Bonhus, a Minneapolis hardware dealer, and was a homemaker there for 36 years. Their marriage ended in divorce.

In 1970, she married a former high school classmate, Dr. Van Murray Sim, and moved to Bel Air. Dr. Sim, who was chief of medical research at Edgewood Arsenal, died in 1995.


A gracious hostess who enjoyed entertaining and cooking, Mrs. Sim wrote to Mrs. Child after the well-known chef's recipe for puff pastry failed.

"In a 1978 typewritten note to my mother, she acknowledged the flaw in the recipe and said she no longer used it," said a daughter, Karen Bonhus Dunlop of Columbia. "She sent one that worked better and on the typed letter included corrections written in her own hand."

In the letter, Mrs. Child made several suggestions on rolling the dough as well as its temperature, and on making sure the rolling surface was sprinkled with enough flour so it wouldn't stick.

"I just think that the important thing is to keep on making it and that you feel at ease with it," Mrs. Child advised, and then admitted, "I don't use the other system at all any more."

Mrs. Sim, who moved to Columbia in 2002, was also an avid reader and perennial gardener.

"We had a private memorial dinner gathering Saturday in her home, using her china, silver and linens. We had canapes prepared by a granddaughter who is a professional chef in New York and wine," Mrs. Dunlop said.

No services will be held.

Also surviving are a son, John Bonhus of Minneapolis; another daughter, Ann Bonhus Smith of Maple Grove, Minn.; a brother, Walter Kinnard of Zionsville, Ind.; seven grandchildren; 11 great-grandchildren; and five great-great-grandchildren.
