Method

 

For Burgers or Fish Balls

1. 1.      In a large bowl, combine the minced carp, onion, capsicum, egg, panko breadcrumbs, paprika, Dijon mustard, lemon zest and juice, capers, garlic, parsley, dill, chives (if using), salt, and pepper.

   2.      Mix gently until just combined – don’t overwork the mixture or the patties will turn tough.

   3.      For burgers: Form into patties approximately 1.5cm thick – 50gm each for sliders, 90gm for standard buns. For fish balls: Wet your hands and roll the mixture into 20gmballs for appetisers, party platters, or soups.

   4.      Place patties or fish balls on a lined tray and refrigerate for 15-30 minutes to firm up. This step stops them falling apart in the pan.

   5.      Preheat your pan or grill over medium–high heat (induction setting 6-7, or a medium to medium–high gas flame). Add a light film of oil.

   6.      For burgers: Cook for4-5 minutes per side until cooked through and lightly charred on the outside. For fish balls: Pan-sear for 3-4 minutes, turning to colour all sides, or poach in a light fish or vegetable broth until firm and opaque throughout.

   7.      Rest for 2 minutes before serving.

Garden Herb Sour Cream Dressing

1. 1.      Combine sour cream, lemon juice, parsley, dill, garlic, Dijon mustard (if using), salt, and pepper in a bowl.

   2.      Mix well until smooth. Taste and adjust seasoning.

   3.      Refrigerate until ready to serve. The dressing holds well in the fridge for up to 3 days in a sealed glass jar.

Notes

Serving Suggestions

1. Lightly toast your bun of choice – whole wheat, charcoal, or brioche all work well.
2. Spread Garden Herb Sour Cream generously on both halves of the bun.
3. Layer with crisp lettuce, sliced tomato, and pickled cucumber.
4. Top with the hot carp burger, or arrange fish balls as a slider or canapé with toothpicks and a ramekin of dressing on the side.
5. Sweet potato wedges: toss with a little olive oil, smoked paprika, salt, and pepper, then roast at 200°C on Fan Plus until golden and crisp.
6. Mixed green salad with cherry tomatoes and a simple lemon vinaigrette.

Notes

1. Carp is available through sustainable fishers and some specialty seafood suppliers. Ask your fishmonger about locally sourced options.
2. Chilling the patties is not optional – a cold mix holds its shape in the pan. If yours are still soft after 30 minutes, freeze for 10 minutes more.
3. Fish balls are well suited to lunchboxes, party platters, or simmering in a light broth with greens and noodles for a quick weeknight soup.
4. Smoked paprika brings more depth than sweet; adjust to how assertive you want the seasoning to be.
5. The dressing doubles as a dip for fish balls, a sauce for grilled fish fillets, or a spread on a fish sandwich.
6. Carp substitutes: any firm white fish can be used in this recipe – try bream, mullet, or ling if carp is unavailable.

 

Fridge Friendly Instructions 

1. Cooked burgers or fish balls: Store in a sealed glass container (400–500gm serves 2) for up to 2 days.
2. Garden Herb Sour Cream Dressing: Keep in a sealed glass jar in the fridge for up to 3 days. Stir before using.

Reheating:

3. Steam oven: 85°C at 100% steam, shelf position 2, for 8-10 minutes until heated through.
4. Conventional oven: 180°C Fan Plus for 8-10 minutes, covered with foil to retain moisture.
5. Stovetop: Reheat in a lightly oiled pan over low heat (induction setting 3-4, or a low to low-medium gas flame), covered, for 4-5 minutes, turning once.
6. Microwave: Cover and heat on 70% power for 1.5-2 minutes. Rest for 30 seconds before serving.

 

Freezer Friendly Instructions

1. Freeze uncooked patties or fish balls only – do not freeze the dressing.
2. Arrange in a single layer on a lined tray, freeze until solid, then transfer to a sealed container or zip-lock bag. Keeps for up to 3 months.
3. Thawing: Thaw overnight in the fridge before cooking, or cook directly from frozen, adding 2-3 extra minutes to the cooking time.
