For the dill yoghurt:

• 3-4 sprigs fresh dill (finely chopped) 
• 1/2 lemon (zested)  
• 1 clove garlic (peeled and finely grated) 
For the pickled cucumbers: 
• 400 g small cucumbers

Method

Ingredients

1. To make the pickles, use a pin to prick each cucumber a few times. Heat the water, vinegar, sugar, salt, bay leaves and mustard seeds, not letting the mixture come to the boil.

2. Pack the cucumbers tightly into a large, sterilized jar and pour over the brine, ensuring the cucumbers are completely covered. Tightly close the lid and leave the cucumbers to pickle for a week. Refrigerate after opening.

3. For the polpette, place the hake, shallot and herbs into a food processor and pulse until finely chopped. In a bowl, combine the hake mixture with the cold mashed potato, egg and flour. Season the mixture with salt and pepper to taste.

4. Use a spoon to shape the mixture into small balls, arranging them on a lined baking sheet. Refrigerate the polpette for an hour to firm up.

5. Pour about 1cm of olive oil into a heavy-bottomed frying pan and carefully lower each polpette into the oil. Fry the polpette over medium heat until brown on all sides, usually 5-8 minutes.

6. To make the dill yoghurt, combine the chopped dill, lemon zest and grated garlic with the Greek yoghurt. Finely chop two pickles and add them to the yoghurt, along with a 10ml of the pickling brine. Season with salt to taste and serve alongside the polpette.

Cook's note: Make the pickled cucumbers at least a week ahead or you can use store-bought pickled gherkins in the dill yoghurt. The pickled cucumber recipe makes 500 ml.
