How to shop for and cook Japanese food at home like a pro

Kate Ng was always apprehensive about cooking Japanese food at home. After a tour of her local Asian supermarket with cookbook author and teacher Atsuko Ikeda, she’ll not only be adding new ingredients to her weekly shop, but new recipes to her weekly rotation

Shopping for Asian ingredients needn’t be as daunting as it first seems (Kate Ng)

The dinner rotation is an unspoken, yet essential schedule. Most of us have five or six reliable recipes tucked away in our back pockets, ready to be pulled out at a moment’s notice. Sometimes this means cooking the same dishes week in, week out.

Venturing outside this routine should be an exciting prospect. Maybe you’ve been inspired by a travel documentary or a new cookbook caught your eye. It doesn’t look that hard, right? But hunting down the right ingredients can feel like a minefield when you don’t really know what you’re looking for or even where to find them.

Shopping well is crucial for success in the kitchen. God only knows the number of times I’ve come home with the wrong thing or given up because I was overwhelmed by the supermarket aisles. What if I end up wasting money on a new meal that turns out catastrophic?

Some cuisines are more daunting than others. Japanese food has such a reputation for perfection that the idea of making anything other than a katsu at home terrifies me. But it wouldn’t be so scary if I had a real-life expert to walk me through the supermarket shelves, show me what to look for and demonstrate that I could indeed be churning out beautiful sushi, delicious broths and other Japanese dishes from my humble kitchen.

Enter: cookbook author and teacher, Atsuko Ikeda, who has offered to take me to an Asian cash and carry to teach me how to shop for Japanese ingredients. We meet at Tazaki, a major distributor of Asian ingredients in the UK that has a warehouse in North Greenwich. It was previously owned by SeeWoo but was acquired by Tazaki last year and is currently in the process of revamping stock.

However, it still carries just about everything you need to get started on a Japanese culinary adventure. Ikeda, who has authored three cookbooks on Japanese small plates, comfort food and sushi, is a frequent visitor. We begin by perusing the fresh ingredients, like daikon (white winter radish), whole lotus root and mustard greens. The whole lotus root can be sliced thinly and fried to make crispy lotus chips, while the snow-white daikon can be grated into sauce or cubed and added to soups.

But we’re starting simpler. Ikeda picks up shimeji mushrooms, small round cap fungi with medium-length stems that grow from a single base. These have an earthier flavour and are denser in texture than regular button or chestnut mushrooms, which means they retain their size and shape a little better. Spring onions, avocado and carrots also make it into the basket, common vegetables that can be found in any supermarket.

Making sushi at home is easier than you might think (Kate Ng)

We move onto carbs and delve into the rice section. As Ikeda is teaching me how to make sushi later, she explains that it is made with Japanese short-grain rice; it has a more glutinous, starchy texture than long-grain rice, which is more popular in the UK. This starchy quality of short-grain rice makes it stickier, an essential feature to make sure sushi rolls and nigiri bites don’t fall apart. A trusted brand for most Japanese ingredients, including sushi rice, is Yutaka, which can be found almost anywhere – I’ve seen it stocked in my local fishmonger. Plenty of other brands abound, with some supermarkets even providing their own brand products, but Ikeda’s recommendation goes straight into my basket.

She points out a variety of noodles, and we’re talking much more than udon. There are bouncy shirataki noodles, almost transparent noodles made from konjac yam that can be eaten hot or cold. You can purchase frozen ramen noodles if you’re experimenting with making your own ramen, but Ikeda winks as she tells me she usually just goes to her favourite ramen shop when she’s craving it. Soba noodles, which can be bought dried, are perfect for the summer when tossed into a cold peanut sauce with an assortment of vegetables. The list goes on and on, but Ikeda reassures me that most noodles are versatile and it mainly depends on what type of texture you’re going for rather than flavour.

Try out different types of miso to better understand their myriad textures and flavours (Kate Ng)

Next is the condiments aisle, where miso resides (can miso be considered a condiment? I’m not so sure). Miso is, of course, a must-have staple. Ikeda points out three types: white miso, sweet rice miso and barley miso. Later, when we taste them, I’m surprised to learn how vastly different they taste from one another. The white miso, which is the most common type used in recipes, has a slight tang and a savouriness that makes your mouth water, while the barley has a deeper, maltier flavour that is mcuh more comforting. I highly recommend buying different types to taste for yourself.

Ikeda also introduces me to yuzugosho, a spicy, tart condiment containing the yuzu fruit and fiery green chillies. It brought a tear to my eye, both from the heat and delicious flavour. Ikeda also teaches me that most commercial wasabi contains more horseradish than wasabi, so buyer beware: if you’re seeking the real deal, you may have to be prepared to shell out more money than you initially think. Some brands are 100 per cent horseradish, marketed as wasabi, so checking the label is essential. The same goes for mirin, a Japanese sweet rice wine which varies in alcohol content. A good rule of thumb is that the cheaper the mirin, the lower the alcohol content.

Soy sauce is another staple for most Asian cuisines, but there are differences. Ikeda prefers to use tamari soy sauce, which is thicker and, I find, not as intensely salty as the soy sauce you usually get in tiny fish-shaped plastic bottles from takeaways. At home, I’m a Kikkoman soy sauce fan, but Ikeda recommends Yutaka’s organic tamari soy sauce for a more mellow, sweeter flavour.

Fishmongers are your best friends when it comes to choosing the best cut of fish for sushi (Kate Ng)

In terms of proteins, it depends on what dish you want. We’re focused on fish, particularly sushi-grade salmon, which you can buy from Tazaki or most fishmongers. This is where I’m especially nervous, because it’s easy to get the cut wrong. However, knowledgeable fishmongers are your best friends when it comes to choosing the cut, so ask plenty of questions. Ikeda shows me how to slice the salmon for different types of sushi rolls and nigiri, as well as how to steam the fish in a baking parchment parcel, slathered in miso and accompanied by the shimeji mushrooms we’d purchased earlier.

You can also add fish roe or masago caviar to your Japanese dishes. The bright orange spheres add a unique saltiness and a satisfying texture to sushi, but can also be used to top rice dishes or stirred through Japanese-inspired pastas. A reliable brand is Elsinore, which can be found in Waitrose.

I still find the idea of making sushi daunting, but the supermarket aisles no longer feel so intimidating now that I have a clearer idea of what to look for. It reminds me of how fun it is to try something new in the kitchen and, armed with cookbooks from the experts, the delicious results will keep me coming back for more.
