Pickled Potato Salad with Garden Peas

Potato salad is a standard, familiar to anyone who has ever been to a barbecue or a buffet table. It’s cheap and easy to make, and can be really delicious when paired with barbecued meats and leafy salads. However, since my Czech friend and colleague, Soña, introduced me to the traditional Czech way of making it with pickled gherkins, peas and dill, I have never looked back.
