dish seems to have taken off with the widespread availability of sliced bread from the 1950s. Early recipes referred to the dish under the seemingly disparaging name of "rat traps", a play on the longstanding nickname of "mouse traps" used for cheese on toast, but also likely a reference to the cylindrical shape, which was similar to commercial rodent traps of the era. The earliest known cookbook recipe for cheese rolls dates from Dunedin's Roslyn Church Jubilee Cookery Book in 1951, with numerous other South Island community cookbooks listing the recipe in the decade that followed. Cheese rolls were not found in any North Island cookbooks, however, until the late 1970s, and the food is still little known north of Waitaki River. The roll gained popularity in the south due to the cold climate and prevalence of soup as a meal option, especially during the frigid winter months. Artisan variations using different cheese and bread varieties have now become a regional feature in restaurants. Fundraisers Occasionally "cheese roll fundraisers" are held, especially by schools and sports groups, like "sausage sizzles" or barbecues. Recent rises in the cost of dairy products have made these fundraisers less profitable than before.
