There’s something irresistibly addictive about the tangy zip of salt and vinegar potato chips. I’ve always been fascinated by how this simple flavor combination can keep you coming back for more. Today, I’m excited to share my elevated take on this classic taste with a homemade version using beautiful fingerling potatoes. These aren’t your ordinary roasted potatoes – they’re a perfect balance of crispy exterior and creamy interior, with that mouth-watering salt and vinegar punch we all crave.
What Makes These Potatoes Special
Before we dive into the recipe, let me share why fingerling potatoes are the perfect choice for this dish. These small, finger-shaped potatoes have a naturally buttery taste and creamy texture that makes them ideal for roasting. Unlike regular potatoes, fingerlings have a thin skin that crisps up beautifully while maintaining that perfect tender interior.
The Science Behind the Perfect Bite
The secret to achieving that intense salt and vinegar flavor lies in a technique I’ve perfected over years of testing. Instead of simply tossing the potatoes in vinegar before roasting, we’ll be using a two-step cooking process that allows the vinegar to penetrate deep into the potato flesh. This method creates layers of flavor that you simply can’t achieve with a quick seasoning.
Essential Ingredients
- 2 pounds fingerling potatoes, mixed varieties if available
- 2 cups white vinegar
- 1 cup malt vinegar
- 2 tablespoons kosher salt, divided
- 1/4 cup extra virgin olive oil
- 2 tablespoons fresh rosemary, finely chopped
- 1 tablespoon fresh thyme leaves
- 4 cloves garlic, minced
- 1 teaspoon freshly ground black pepper
- Flaky sea salt for finishing
Equipment Needed
- Large pot with lid
- Colander
- Large rimmed baking sheet
- Parchment paper
- Kitchen thermometer
- Metal spatula
The Perfect Preparation Method
- Initial Preparation
- Thoroughly wash the fingerling potatoes under cold water
- Remove any blemishes or sprouts
- Pat completely dry with paper towels
- Cut any larger potatoes lengthwise to ensure even cooking
- The Vinegar Bath (Key Step!)
- Combine white and malt vinegar in a large pot
- Add 1 tablespoon kosher salt
- Bring the mixture to a gentle boil
- Add potatoes and reduce heat to maintain a simmer
- Cook for 20-25 minutes until fork-tender but not falling apart
- The Crucial Rest
- Drain potatoes in a colander
- Let them steam dry for 5 minutes
- Return to the empty pot and shake gently to rough up the surfaces
- This creates more surface area for crisping
- The Roasting Process
- Preheat oven to 425°F (220°C)
- Line baking sheet with parchment paper
- Toss potatoes with olive oil, herbs, remaining salt, and pepper
- Arrange in a single layer with plenty of space between each potato

| Refrigerator | 3-4 days | Airtight container |

Frequently Asked Questions
Q: Can I use regular potatoes instead of fingerlings?
While you can use other potato varieties, fingerlings are ideal because of their size and texture. If substituting, I recommend small Yukon Gold potatoes cut into similar-sized pieces.
Q: Why use two types of vinegar?
The combination of white and malt vinegar creates a more complex flavor profile. White vinegar provides the sharp tang, while malt vinegar adds depth and subtle sweetness.
Q: My potatoes aren’t getting crispy enough. What am I doing wrong?
The most common cause is excess moisture. Make sure to thoroughly dry the potatoes after the vinegar bath and give them plenty of space on the baking sheet. Overcrowding leads to steaming instead of roasting.
Q: Can I make these ahead for a party?
While they’re best fresh, you can par-cook them in the vinegar solution up to a day ahead. Store in the refrigerator, then complete the roasting process just before serving.
Q: Are these too vinegary for kids?
The roasting process mellows the vinegar flavor significantly. However, you can reduce the vinegar bath time to 15 minutes for a milder taste that’s more kid-friendly.
