Cuckoo manufacturers small home appliances, notably Korean-style pressure rice cookers. Korean-style cookers (0.8 kg to 0.9 kg cooking pressure) typically gelatinize rice starches more completely than Japanese-style cookers (0.4 kg to 0.6 kg cooking pressure) resulting in a more glutinous and marginally more nutritious cooked rice. In South Korea Cuckoo is the top-selling brand of rice cooker. In 2002, Cuckoo started selling to distributors in New York and Los Angeles. In late 2016, Cuckoo established its first American branch, Cuckoo Electronics America, Inc. in Los Angeles, California.
