Agriculture and fisheries are very important industries for Ibaraki, and the prefecture has been the largest source of agricultural produce for the Tokyo Central Wholesale Market for the last 11 years running. The prefecture boasts the largest output in Japan of products such as melon, sweet potatoes, mackerel, and prawns, amongst others. Famous local delicacies include angler-fish hotpot, which you can enjoy in the winter, and natto (fermented soy beans), which goes great with cooked white rice.
Personally, I love tofu, miso, and pretty much anything and everything that comes from the sea - but I often find that cooking tempura and yakitori for my British friends is the easiest way to spark their interest in Japanese home-cooking. However, the dish that I'd like to introduce combines two of my favourite things - miso and mackerel. Although not exactly an Ibaraki delicacy, the dish could be said to be a bit like Ibaraki itself. It may not look particularly flattering or exciting at first glance, but you will find that it actually tastes wonderful. It is also not that hard to find the necessary ingredients in British supermarkets, so give it a try!
