In the United Kingdom, it has been produced by companies including H. J. Heinz Company and Crosse & Blackwell. Heinz Salad Cream was the first brand developed exclusively for the United Kingdom market. When first created in the Harlesden (London) kitchens of Heinz in 1914 the preparation was done by hand. The jars were packed in straw-lined barrels- 12 dozen in each. The work schedule was 180 dozen jars a day- with a halfpenny a dozen bonus if the workforce could beat the target. 
Salad cream is available in most supermarkets in Canada and Ireland, as well as in Australia, where its taste may closely resemble that of "mayonnaise" as it is produced in that country.
Salad cream was not readily available in the United States until the 21st century; however, with the large population of British expatriates, especially in the Northeast, it is becoming more common. Apart from many expat stores, major retail supermarket chains such as New York-based Wegmans, Maine-based Hannaford, Massachusetts-based Stop and Shop, Florida-based Publix, Michigan-based Meijer, and California-based Fresh & Easy (formerly owned by British Tesco) now[update] sell salad cream as a regular item. Many supermarkets sell national and store brands of salad dressing which resemble salad cream.
