Step-by-Step Instructions

Step 1: Boil the Potatoes

  1. Prepare the Potatoes:
    • Begin by scrubbing the 1 kg of potatoes under cold running water to remove any dirt. Since we are keeping the skins on, it’s important to make sure they are thoroughly cleaned.
    • Cut the potatoes into evenly sized chunks (about 1.5-inch pieces). This ensures that they cook at the same rate.
  2. Cook the Potatoes:
    • Place the potato chunks in a large pot and cover them with cold water. Add 1 teaspoon of salt to the water to season the potatoes while they cook.
    • Bring the water to a boil over medium-high heat, then reduce the heat to a simmer. Let the potatoes cook for about 15-20 minutes or until they are fork-tender but not mushy. Test them by inserting a fork into a piece; it should slide in easily.
    • Once cooked, drain the potatoes and let them cool slightly. The potatoes should still be warm when you dress them with the vinaigrette to absorb all the flavors.

Step 2: Prepare the Mustard Vinaigrette

  1. Make the Dressing:
    • While the potatoes are cooking, prepare the mustard vinaigrette. In a medium bowl, whisk together the 4 tablespoons of wine vinegar, 2 tablespoons of whole-grain mustard, and 100 ml of olive oil.
    • Season the vinaigrette with salt to taste. You can also add freshly ground black pepper if you like a bit of extra spice.
    • Whisk the mixture well until it emulsifies into a smooth dressing. If you want the vinaigrette to be slightly tangier, you can adjust the amount of vinegar to your liking.

Step 3: Assemble the Potato Salad

  1. Combine Potatoes and Dressing:
    • While the potatoes are still warm, transfer them to a large mixing bowl. Pour the prepared mustard vinaigrette over the potatoes. Toss gently, making sure each piece of potato is coated with the tangy dressing.
  2. Add Fresh Herbs:
    • To enhance the flavor and add some freshness, add the chopped green onions and chopped parsley to the bowl. Toss again until everything is evenly mixed.
  3. Let the Salad Rest:
    • For the best flavor, let the salad rest for about 15-20 minutes before serving. This allows the potatoes to soak up the vinaigrette and the flavors to meld together.

FAQs

Can I make this potato salad ahead of time? Yes, this potato salad is ideal for making ahead. In fact, it often tastes better the next day as the flavors have more time to develop. Simply store it in an airtight container in the refrigerator for up to 3 days.

Can I use a different type of vinegar? Yes, you can use other types of vinegar like apple cider vinegar or white wine vinegar. However, red wine vinegar is recommended for a nice balance of tanginess and sweetness.

Can I add other vegetables to this salad? Absolutely! You can add cooked carrots, peas, or even boiled eggs to the salad to make it more hearty and colorful. Just make sure to adjust the seasoning as needed.

Tips for Making the Best Potato Salad

  1. Use Waxy Potatoes:
    For the best texture, use waxy potatoes like Yukon Gold or red potatoes. They hold their shape better when cooked and don’t become mushy.
  2. Warm Potatoes Work Best:
    Make sure the potatoes are still warm when you mix them with the dressing. This allows the potatoes to absorb the vinaigrette more effectively, creating a more flavorful dish.
  3. Don’t Overcook the Potatoes:
    Be careful not to overcook the potatoes, as they can turn mushy. Test them by piercing with a fork—if the fork slides in easily but the potato still holds its shape, it’s done.
  4. Adjust the Dressing to Your Taste:
    If you prefer a tangier salad, increase the amount of vinegar in the dressing. Alternatively, if you like a milder flavor, reduce the vinegar and use a bit more olive oil.

Storage Tips

  • Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors will continue to develop over time, so the salad can taste even better the next day.
  • Freezing: It’s not recommended to freeze potato salad as the texture of the potatoes will change upon thawing.
