Instructions

Step 1

Cook the potatoes: Place the potatoes in a pan of salted water and bring to the boil. Cook for 15–20 minutes, until tender but not falling apart. Drain and allow to cool slightly.

Step 2

Prepare the dressing: In a large bowl, mix together the mayonnaise, mustard, vinegar, salt and pepper.

Step 3

Add the onion and dill: Stir in the chopped red onion and most of the dill (keep a little for garnish).

Step 4

Combine: Cut the cooled potatoes into bite-sized pieces and gently fold into the dressing, being careful not to break them up too much.

Step 5

Taste and adjust: Add more mustard, vinegar, salt or pepper to taste.

Step 6

Serve: Sprinkle with the remaining dill and chill for at least 15 minutes before serving to let the flavours develop.
