Onion dip

French onion dip or California dip is an American dip typically made with a base of sour cream and flavored with minced onion, and usually served with potato chips as chips and dip. It is also served with snack crackers and crudités. It is not French cuisine; it is called "French" because it is made with dehydrated French onion soup mix. French onion dip, made of sour cream and instant onion soup, was created by an unknown cook in Los Angeles in 1954. The recipe spread quickly and was printed in a local newspaper. The Lipton company promoted this mixture on the television show Arthur Godfrey's Talent Scouts in 1955, and early on, it was known as "Lipton California Dip", but soon simply as "California Dip". A Lipton advertising campaign promoted it on television and in supermarkets. The recipe was added to the Lipton instant onion soup package in 1958. Around the same time, a similar recipe, but made with reduced cream, was created in New Zealand and became very popular.
