Singapore chilli crab

Chilli crab (辣椒螃蟹): mud crab in sweet-spicy tomato and egg sauce

Chilli crab was first sold from a pushcart on the Kallang river in the 1950s and is now the dish visitors queue for along Singapore's East Coast seafood strip. Big mud crabs are cut up, wok-fried and simmered in a thick, sweet, tangy and gently hot sauce of chilli, tomato and garlic, which is then silked with beaten egg. Everyone eats with their hands and mops up the sauce with fried or steamed mantou buns. It is a weekend or celebration meal, messy and loud. Buy crabs live or freshly cooked the same day from a fishmonger you trust. Discard any live crab that doesn't move, smells of ammonia or has a cracked, leaking shell. The common mistake is boiling the sauce after adding the egg, which scrambles it into lumps; pour it in a thin stream over a low heat. Chef's tip: ask the fishmonger to clean and quarter the crab for you, and crack each claw lightly with the back of a cleaver so the sauce soaks in.

Method

0/10 done
  1. Step 1: Keep live 2 mud crabs, live or very fresh in the fridge, covered with a damp cloth, and cook them the same day. Check each piece after cleaning: the flesh should smell of the sea, never sour.

  2. Step 2: Blitz 6 fresh red chillies, 4 shallots, 6 cloves garlic, 1 oz fresh ginger and 1 tsp toasted shrimp paste (belacan) to a coarse paste with 1 tbsp of the 2 ½ tbsp water.

    5 min
  3. Step 3: Pat the crab pieces dry and dust the cut sides lightly with 2 tbsp cornflour.

    3 min
  4. Step 4: Heat 4 tbsp vegetable oil in a wok over a high heat. Fry the crab in two batches, 3–4 minutes each, until the shells turn bright orange-red. Lift onto a plate; it will finish cooking in the sauce.

    8 min
  5. Step 5: Lower the heat to medium. Fry the chilli paste in the oil left in the wok for 3–4 minutes, stirring, until it smells sweet and the oil turns red.

    4 min
  6. Step 6: Add ½ cup tomato ketchup, 3 tbsp sweet chilli sauce, 1 ½ tbsp sugar, 1 tsp salt, 1 tbsp rice vinegar and the rest of 1 ½ cups water. Bring to the boil and taste: it should be sweet, tangy and gently hot.

    2 min
  7. Step 7: Return the crab with its juices, cover and simmer over a medium heat for 6–8 minutes, turning the pieces twice, until the meat inside the thickest claw is opaque white and firm all the way through.

    8 min
  8. Step 8: Stir in 1 tbsp cornflour and bubble for 1 minute until the sauce thickens.

    1 min
  9. Step 9: Turn the heat to low. Pour in 2 eggs in a thin stream while stirring slowly, so the egg sets in soft ribbons. Turn off the heat as soon as it is just set.

    1 min
  10. Step 10: Scatter with 2 spring onions and 1 handful fresh coriander and serve at once with 8 fried or steamed mantou buns for the sauce, crab crackers, picks and finger bowls. Eat crab the day it is cooked; don't keep cooked crab at room temperature for more than 2 hours.

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.

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.

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.
