Kapr na černo
Carp in dark sweet-sour sauce
Kapr na černo: old Czech Christmas Eve carp in dark sweet-sour sauce
Before fried breaded carp took over the Czech Christmas Eve table, families in Bohemia served kapr na černo, 'black carp': fish simmered in a dark, glossy, sweet-sour sauce of root vegetables, gingerbread, prunes, nuts and dark beer. It is rich and spiced, closer to a medieval feast dish than to the modern menu, and served with bread dumplings or potatoes. This version uses a non-alcoholic dark malt drink so the sauce is alcohol-free; adults may use dark beer. Chef's tip: grate the gingerbread finely, so it melts into a smooth sauce rather than leaving soggy crumbs.

Method
0/6 doneStep 1: Fry 1 onion, 1 carrot, 3 ½ oz celeriac and 1 parsley root or parsnip in 2 tbsp sunflower oil over a medium heat for 10 minutes, until softened and browning.
10 minStep 2: Add 1 bay leaf, 4 allspice berries, 6 black peppercorns, 1 ½ cups non-alcoholic dark malt drink or dark beer, 1 ¼ cups water and 2 tbsp red wine vinegar and simmer for 20 minutes, until the vegetables are very soft.
20 minStep 3: Take out the bay and spices and blend the sauce until smooth. Return to the pan and whisk in 2 ⅞ oz dark gingerbread (perník); simmer for 5 minutes until thick and glossy.
5 minStep 4: Add 2 ⅞ oz pitted prunes, 1 ⅜ oz raisins, 1 ⅜ oz walnuts, 1 oz flaked almonds, 1 tbsp sugar, ½ lemon and 1 tsp salt. Taste: it should be sweet, sour and spiced in balance. Adjust with more vinegar or sugar.
Step 5: Lay 1 ¾ lb carp fillets or steaks in the sauce, spoon some over, cover and simmer very gently for 12–15 minutes, until the fish is opaque and flakes easily. A common mistake is letting the sauce boil, which breaks up the carp and catches on the base.
15 minStep 6: Serve with bread dumplings or boiled potatoes.

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.
