Why Vinegar? The Science Behind the Crisp

First, let’s dive a bit into the science. The acidity from the vinegar helps break down the surface of the potato, which, when fried, creates that delightful, sought-after crispy exterior. It’s a game-changer, really.

Shopping List for Ultimate Vinegar Crispy Fries:

  1. Potatoes: Ideally, go for high-starch ones like Russets.
  2. Oil for frying: Vegetable oil, canola oil, or peanut oil are great choices.
  3. Cornstarch: Available in the baking aisle.
  4. White Vinegar: Can be found with other vinegars or in the condiments aisle.

Hints & Hacks for Perfect Crispy Fries:

  • Potato Selection: High-starch potatoes like Russets or Idaho are the best. They hold less moisture, ensuring your fries get that perfect crisp.
  • Freshness Factor: Always use fresh potatoes. Older potatoes might have a higher sugar content, which could lead them to brown faster when frying.
  • Cutting Technique: A mandolin slicer can help achieve uniform slices quickly. But if using a knife, always aim for consistent thickness to ensure even cooking.
  • Rinsing: After cutting, rinse the fries in cold water to remove excess starch. This prevents them from sticking together while frying and helps achieve a better color.
  • Double Fry Technique: For an even crispier result, you can employ the double fry technique. Fry once at a lower temperature (325°F or 165°C) until they’re just cooked through, then drain and let them cool. Fry again at a higher temperature (375°F or 190°C) until golden.
  • Safety First: Always be careful when working with hot oil. Use a thermometer to ensure the oil is at the right temperature, and always lower the fries gently into the oil to avoid splashes.
  • Seasoning: Salt your fries immediately after frying. The residual heat helps the salt stick better. You can also get creative with seasonings, using herbs, garlic powder, or even cheese!
  • Serving: Serve the fries immediately for best results. If you need to hold them for a short period, keep them in an oven set at a low temperature to retain their crispness.
  • Dipping Sauces: While ketchup is a classic choice, consider branching out with aioli, honey mustard, or a spicy mayo.
    Remember, practice makes perfect! The more you make these fries, the better you’ll get at perfecting them to your liking. Enjoy your cooking adventure! 🍟


  • Potatoes
  • Oil for frying
  • 1 heaping tablespoon of cornstarch
  • 2 tablespoons of white vinegar
  • Water

Step-By-Step Guide to the Ultimate Crispy Fries:

  1. Select Your Spuds: Choose high-starch potatoes like Russets. These hold less moisture and guarantee a crispier outcome.
  2. Cutting Matters: Cut your potatoes uniformly to ensure even cooking. Aim for a thickness of about ¼ to ½ inch.
  3. The Vinegar Bath: Here’s where the magic happens. In a large pot, combine enough water to submerge your fries and stir in 2 tablespoons of white vinegar. Add your sliced potatoes and bring to a boil. Once boiling, let them cook for about 5 minutes. Drain and let them dry thoroughly.
  4. Cornstarch Coating: This is another trick to add an extra layer of crunch. In a large bowl, sprinkle the cornstarch over your par-boiled fries. Toss them gently to ensure an even coating.
  5. Time to Fry: Heat your oil to 350°F (175°C). Fry your potatoes in batches, making sure not to overcrowd the pot. Fry until they’re golden and crisp. This should take around 3-5 minutes.
  6. Drain and Serve: Once done, place them on a paper towel-lined plate to drain excess oil. Salt immediately and serve while hot!

The Secrets Behind the Perfect Recipe:

While the vinegar bath is the star of the show, other elements also play crucial roles:

  • High-starch potatoes: As mentioned, these potatoes hold less moisture, leading to a crisper finish.
  • Uniform Cutting: This ensures even cooking, making every bite consistently delicious.
  • Cornstarch: Acts as a double armor, creating an extra crunch factor that sets these fries apart.

Frequently Asked Questions (FAQs):

    Is the cornstarch step mandatory?
  • It’s optional but highly recommended for that extra crunch.
    What oil is best for frying?
