Herring Salad

Originally from: Dagi (with the pickled herring recipe from https://honest-food.net/swedish-pickled-herring).

Note: this is a traditional German salad.
Note: needs to be left overnight for at least two, preferably three, nights.

Serves: 6.

Ingredients

For the pickled herring (if you aren't just buying pickled herring):

• 500 gm fresh or frozen herring fillets
  
• 500 ml 1:16 solution of salt in water
• 1 red onion, very thinly sliced
• 1 lemon, very thinly sliced
  
• 500 ml white wine vinegar
• 1 tsp mustard seeds
• 2 tsp whole allspice
• 2 tsp black peppercorns
• 3 cloves

For the salad:

• 500 gm pickled herring [see above]
• 250 ml double cream
• 250 ml natural yoghurt
  
• 3 Granny Smiths apples, cut into small cubes (no need to peel them)
  
• 100 gm pickled onion [can be taken from the pickled herring above]
• 100 gm chopped (not sliced; they need to be bite-sized) gherkins
• 1.5 tsp whole grain mustard
• 0.25 tsp salt
  
• lots of freshly ground black pepper
  

Method

1. Cut the herring fillets into ~6 chunks each and submerge them in the salted water overnight in the fridge.
2. Mix together the other liquid pickling ingredients.
3. Layer the herring fillet with the onion and lemon slices.
4. Pour the liquid pickling ingredients over the top and leave in the fridge overnight.
5. Remove the herring pieces from the liquid and mix them into the other salad ingredients in a bowl; leave overnight in the fridge if you can.
6. Serve.
