Tenmusu

Prawn tempura rice balls

Tenmusu (天むす): Nagoya rice balls with a prawn tempura inside, wrapped in nori

Tenmusu, short for tempura musubi, began in Tsu and became a Nagoya speciality: small salted rice balls with a crisp little prawn tempura poking out of the top, wrapped in nori and sold in boxes at Nagoya Station as a travel lunch. The common mistake is wrapping hot, crunchy tempura straight into the rice, so it steams soft; let it cool on a rack first. Use raw prawns that smell of the sea; throw away any that smell of ammonia. Chef's tip: brush the cooled tempura with a quick sweet soy dip before you shape the rice round it, which is the Nagoya secret to its flavour.

Method

0/6 done
  1. Step 1: Make 3 shallow cuts across the underside of each of 12 raw king prawns and press flat to stop them curling. Pat dry and dust lightly with 1 tbsp of the 2 ⅛ oz plain flour.

  2. Step 2: Heat 2 ½ cups vegetable oil to 350°F. Whisk 1 egg yolk into ½ cup ice-cold sparkling water, then stir in the rest of the flour with chopsticks; leave it lumpy.

  3. Step 3: Dip the prawns in batter and fry 4 at a time for 2–3 minutes, until crisp, pale gold and the prawns inside are pink and opaque. Drain on a rack and cool.

    8 min
  4. Step 4: Warm 2 tbsp soy sauce, 1 tbsp sugar and 2 tbsp water until the sugar dissolves. Dip each cooled prawn briefly in it.

    1 min
  5. Step 5: Wet your hands and rub them with a little 1 tsp salt. Take 50 g of 1 ⅓ lb freshly cooked Japanese short-grain rice, flatten it in your palm, set a prawn on top with the tail sticking out, and close the rice around it into a small triangle.

  6. Step 6: Wrap a strip of 3 nori sheets round the base of each ball. Eat the same day; keep cool and pack with an ice pack.

Moreton Bay bugsSlipper lobster with garlic butter

Moreton Bay bugs are the flat, shovel-nosed slipper lobsters caught off the Queensland coast around Brisbane and the Sunshine Coast, and for Queenslanders they are a summer treat, split and grilled at the beach house. The tail meat is sweet and rich, somewhere between lobster and prawn. Buy them raw, frozen or fresh, from a fishmonger and ask them to halve them if you like. A common mistake is overcooking, which makes the meat rubbery; it is ready the moment it turns white. Chef's tip: grill flesh side down first to mark it, then turn and baste in the shell.

Midia saganakiMussels with tomato and feta

Thessaloniki is Greece's mussel capital, with farms in the Thermaic Gulf a few kilometres from the seafront ouzeries where this two-handled pan arrives, still bubbling, at the table. Mussels steam open in a quick sauce of peppers, tomato and chilli, and crumbled feta melts into the juices at the end. Bread is essential. The classic version adds a splash of ouzo; this one is alcohol-free, using a pinch of fennel seed for that aniseed note (add 2 tbsp ouzo with the tomatoes if you like). Common mistake: overcooking — take the pan off the heat as soon as the shells open. Chef's tip: buy mussels on the day and keep them in the fridge in a bowl covered with a damp cloth, never in water.

All i pebreEel and potato paprika stew

In El Palmar and the other villages around the Albufera lagoon south of Valencia, the restaurants that are famous for paella serve something older first: all i pebre, "garlic and pepper", a brick-red stew of lagoon eel and potatoes thickened with a pounded almond and fried-bread picada. It is rich, garlicky and gently hot, eaten with bread to mop up the sauce. Ask your fishmonger to skin and cut the eel, and handle it with gloves: raw eel blood is irritating, though harmless once cooked. If you can't find eel, monkfish or hake works well. A common mistake is letting the paprika burn; it turns bitter in seconds, so add it off the heat. Chef's tip: break the potatoes with a knife instead of cutting cleanly; the rough edges release starch and thicken the sauce.
