When you mention Japanese soup, the dish that springs to mind instantly is the timeless, classic miso soup with tofu and wakame seaweed; in the colder months of the year however, and particularly on the pork-loving island of Kyushu, another soup reigns as king- Tonjiru. Sometimes called Butajiru, both names literally meaning pork soup, it is a much heartier affair than the standard bowl of miso; enhanced with strips of braised pork belly, a selection of root vegetables, blocks of springy jelly-like konnyaku and deeply savoury shreds of mushroom, a bowl of this wintery, sustaining soup quickly starts to feel like a meal in itself. Possibly not a soup suited to breakfast time due to its more stew-like consistency, it makes a fantastic accompaniment to both meaty dishes and also beer, and as such it finds its way onto the menus of many izakaya, tonkatsu restaurants and gyudon joints. Outside of restaurants, we’ve found it for sale at religious festivals, farmers’ markets, sporting events and anywhere that large numbers of people gather together and need feeding; a homely classic full of earthy flavours that brings diners together and ignites childhood memories of mothers’ cooking.
At the foundation of nearly all Japanese food is a handful of key flavours and ingredients; salty fermented soy products such as miso and soy sauce; sweet mirin and aromatic sake rice wines; and the underlying essence of the sea- a delicate, smoky, ocean scented stock called dashi. At its most basic and purest form, dashi is simply dried kombu seaweed, rehydrated and steeped in water until it releases all of its delicious, rich minerals creating a savoury broth to boost the taste of any dish. More complicated versions of the liquor add sawdust-like smoked bonito flakes, small dried fish such as sardines or anchovies and maybe even a handful of woody, earthy tasting shiitake mushrooms to supercharge the umami qualities of this liquid flavour bomb.
Umami- the fifth taste after sweet, salty, bitter and sour- is a loan word from Japanese, literally meaning ‘delicious flavour’ and it describes the brothy, savoury, meaty taste identified when the tongue’s receptors react to the presence of glutamic acid in food. Dried kombu is particularly rich in glutamic acid (so much so that you can even see crystals of it on the seaweed’s surface, looking like a white powdery bloom) and the savoury aspects become even stronger when combined with bonito flakes thanks to the synergistic relationship between glutamates and the inosinates present in nearly all dried seafood. Only explained by science in the early twentieth century, the cooks of Japan have known about the mouth watering qualities of combining these flavours together for centuries, using dashi in everything from pancake batters to soups and stews.
Nowadays there are plenty of very good instant dashi powders and granules easily available in supermarkets- we use them regularly when we don’t want the dashi itself to be an overly prominent flavour in the finished dish- but nothing really compares to making your own, adjusting the seasoning to your liking, adding more or less of one ingredient or another, or perhaps even adding a completely new ingredient (the addition of smoked bacon or air dried ham creates an unconventional but intoxicatingly heady dashi that goes brilliantly with darker, red miso soups). We’re certain that after you’ve tried making your own dashi, you’ll want to always keep a packet of kombu and katsuobushi handy in your store cupboard at all times.
PS. Whatever you do, don’t throw away the used flavourings after you’ve strained your broth, make them into a delicious seasoning for your rice by following our recipe for homemade furikake or cook them up again to make niban dashi.
When one thinks of ramen, deep steaming bowls of unctuous porky broth often spring to mind, accompanied by slices of meltingly fatty meat, perhaps a haphazard pile of spicy spring onions and some savoury marinated menma. By no means is this the only way the Japanese crave their soup noodle fix though, with areas of the country creating their own specialities reflecting their own tastes and regional produce. One version of the dish we were recently introduced to and have reproduced here is the poetically named Kitano Megumi Ramen, or the Blessing of the North Ramen; a creamy, soothing concoction that rejoices in using everything good from the most northerly island- Hokkaido.
Thanks to its cooler climate and the massive expanses of pasture land that cover Hokkaido- the least developed of the main islands- it is able to support a thriving dairy industry. Smooth milk and rich, creamy butter from the island command a high price because of their superior quality- they proudly display their heritage and nearly always have the iconic outline of Hokkaido prominent on their packaging. Similarly, prime examples of sweetcorn grow in abundance on the rich, volcanic soil and the kernels are often found bobbing around playfully in the salty, miso based ramen broths favoured in Sapporo, surprising your palate with a pop of freshness. Particularly juicy cooked hams crafted from Sangen pigs complete this cornucopia of produce from the rugged north, creating a uniquely Hokkaidoan interpretation of the classic ramen.
To compliment the savoury, milky soup we’ve created a dashi flavoured compound butter to crown the ramen, but don’t feel limited to using it on just this dish- a pat or two of the smoky, seaweed infusion makes a fantastic oozy topping for a rib-eye steak or pork chop, and when tossed into steamed greens it lifts a relatively basic vegetable and turns it into something very special.
According to the lunar calendar today is Setsubun- the day before the start of spring, a sort of New Year’s Eve. It is believed that at the start of a new year, the mortal world and the spirit world move closer together than normal, so spirits can wander more easily into our world. Because of this, people all over Japan take part in purification rituals to ward off bad fortune for the year to come, traditionally using fukumame (‘lucky beans’, roast soybeans) to chase demons and evil spirits from their homes and invite good luck in. These beans are either thrown out of the door or at a representation of an evil spirit- normally a member of the family, wearing an oni mask- whilst chanting “Oni wa soto! Fuku wa uchi!” or “Demons out! Luck in!” It is also traditional to eat a roasted soybean for each year of your life, plus an extra one for the coming year, to bring good health.
Soybeans are a ubiquitous part of Japanese cuisine, used in the production of tofu, soy sauce and miso amongst other foodstuffs. To commemorate Setsubun we’ve combined puréed soybeans and miso paste to make gojiru, a thick warming soup, full of vegetables, that’s sure to bring you health for the whole of the year.
