That sound. That sharp, almost mineral crunch when your tooth sinks into a fresh fry. We all know it — we look for it every time — and yet, most of our homemade fries end up soft, soggy, and disappointing. This technique changes that.
Ingredients :
- The potatoes — Go for a floury variety: Bintje, Agria, or Russet if you can find them. These are the ones that provide the melting interior. Firm-fleshed potatoes — like Charlotte or Ratte — don’t hold up as well to frying. The final texture is denser and less pleasant.
- White vinegar — Ordinary white vinegar, not cider or balsamic. It must be neutral. Its role: the acidity tightens the surface of the potato and helps gelatinize the outer starch. This translates directly into a sharper crust. Two tablespoons for a large bath is enough.
- Cornstarch — Classic cornstarch (like Maizena) does the job perfectly. No flour — it absorbs oil and softens. Starch, on the other hand, creates a light, very fine crust upon contact with hot oil. One heaping tablespoon per good batch of fries.
- Frying oil — Sunflower or peanut oil. Neutral in taste with a high smoke point. Avoid extra virgin olive oil — it burns too quickly and imparts a flavor that doesn’t go well with fries at all.
