Don't buy shop brought I make my own recipie below
Small potatoes ie salad or new when in season or any small potatoes will do (boiled until tender)
1 small onion chopped
Mayonnaise
Chopped chives
Salt and peper to taste
Place potatoes when boiled into a bowl add onions and mayo (enough to cover )and mix,add chives and salt and peper to taste place in the fridge until ready
My family love it they can not get enough ,but they won't let it sit in the fridge I am lucky to get any when I make it,it never lasts long ,most of the time as soon as I make it ,they eat it
