Pro Tips
For the crispiest smashed potato salad, let the boiled potatoes steam dry completely before roasting, since excess moisture can keep the edges soft. Give the potatoes plenty of space on the baking tray so they roast rather than steam, and press them gently with the bottom of a glass so they flatten without falling apart. Be generous with the olive oil, and turn the potatoes halfway through cooking to help both sides become golden and crisp. Once roasted, allow them to cool before adding the dressing, as very hot potatoes can quickly soften the crispy exterior. Start with only half of the dressing, then add more as needed so the salad stays creamy without becoming too wet. Finally, fold everything together gently and finely chop the gherkins, cucumber, red onion, chives, and dill so the fresh, tangy flavours are evenly distributed throughout the salad.
