Mizu shingen mochi (Yamanashi raindrop cake)
Crystal-clear agar water cake with roasted soy flour and black-sugar syrup
Mizu shingen mochi comes from Hokuto in Yamanashi, at the foot of the Southern Alps, where a sweet shop first set the local spring water into a trembling, glass-clear dome. It is a summer sweet, eaten in the heat of July and August, and it has to be eaten within half an hour of being made, before it starts to weep. There is almost no flavour of its own: the point is the cool, melting texture, with nutty kinako and dark kuromitsu syrup poured over at the table. Despite the name it is not a rice mochi at all, and it is naturally egg-free. Agar, a seaweed setting agent, holds the water in shape; using just enough to set it makes it melt on the tongue. Serve with green tea. Chef's tip: boil the agar hard for a full 2 minutes; just warming it is the common mistake, and the domes stay liquid in the mould.

Method
0/6 doneStep 1: Simmer 2 ⅛ oz Okinawan black sugar or dark muscovado sugar with 3 ½ tbsp water in a small pan over a medium heat for 4–5 minutes, until dissolved and slightly syrupy. Cool; it thickens as it cools.
5 minStep 2: Whisk ⅛ oz agar powder and ⅓ oz sugar into the cold 1 ¾ cups soft mineral or filtered water in a small pan until there are no lumps.
Step 3: Bring to the boil over a medium-high heat, stirring, then keep it at a rolling boil for 2 full minutes so the agar dissolves completely.
4 minStep 4: Take off the heat and cool for 3–4 minutes, skimming off any foam so the cakes stay clear.
4 minStep 5: Pour into 4 half-sphere moulds (or small round bowls), cover and chill for 1 hour, until set but still with a soft wobble when shaken.
60 minStep 6: Ease each cake out onto a plate by running a wet finger around the edge. Dust with 4 tbsp kinako (roasted soy flour), pour over the syrup and eat within 30 minutes.

Miso soup
Miso soup (味噌汁) is drunk every day in homes all over Japan, at breakfast as well as dinner, beside a bowl of rice. The base is dashi; this vegan version uses kombu and dried shiitake instead of bonito, which gives it a deep, rounded flavour. Silken tofu and wakame seaweed are the classic fillings. It takes ten minutes; just remember not to boil the miso. Chef's tip: add the miso at the very end and never let it boil. Boiling kills the miso's fresh, fermented aroma; Japanese cooks say the soup should only 'smile', with the surface barely trembling.
Yaki onigiriGrilled rice balls
Yaki onigiri (焼きおにぎり) are rice balls grilled until they form a crisp, toasty crust, then brushed with soy sauce glaze. They are eaten all over Japan, at izakaya, at barbecues and from the freezer section, as a snack or with miso soup. The inside stays soft and steamy while the outside crackles. Best eaten hot, straight from the pan. Chef's tip: let the shaped rice balls dry for 10 minutes before they go in the pan. A drier surface forms a better crust and won't stick, and the glaze goes on only at the end so it doesn't burn.
Kartoshka cakeCocoa and cake crumb truffles
Soviet cafés and school canteens sold these knobbly brown 'potatoes' for a few kopecks, and they began as a thrifty way to use up sponge and biscuit trimmings at the bakery. Crumbs are bound with butter and sweetened condensed milk, flavoured with cocoa and vanilla, shaped into little potatoes, rolled in cocoa and finished with two dabs of pale butter cream for the sprouts. They are fudgy and dense like a brownie truffle, need no oven, and children love making them. Traditional bakers added a spoonful of rum, an optional extra for adult batches only; this version is alcohol-free with vanilla. The usual slip is coarse crumbs, which make the potatoes crack, so blitz them as fine as sand. Chef's tip: chill the shaped potatoes for at least 20 minutes so they hold their shape and slice cleanly.
Perfect for:Summer coolers
