Ingredients

Triple-Cooked Kennebec Fries

  • 1 lb Kennebec potatoes (sub: Russet potatoes)
  • 2 cups olive oil for frying (sub: Vegetable oil)
  • 1 tsp kosher salt (sub: Sea salt)
  • ½ tsp pimentón dulce (sub: Sweet paprika)

Jamón-Sherry Reduction

  • ½ cup dry Fino sherry (sub: Dry white wine with a splash of vinegar)
  • 2 tbsp high-quality jamón ibérico, minced (sub: Prosciutto)
  • 1 small shallot, finely minced (sub: Yellow onion)
  • 1 tbsp extra virgin olive oil (sub: Unsalted butter)

Garnish

  • 1 slice jamón ibérico, thinly crisped in a pan (sub: Crispy prosciutto)
  • 1 tsp fresh flat-leaf parsley, finely chopped (sub: Fresh cilantro)
  • ¼ tsp pimentón de la Vera (sub: Smoked paprika)

How to Make Triple-Cooked Kennebec Fries with Jamón-Sherry Reduction

Triple-Cooked Kennebec Fries:

  1. Cut potatoes into uniform batons, 1/2 inch thick.
  2. Simmer in salted water for 8 minutes until tender but holding shape; drain and dry completely.
  3. Fry at 300°F (150°C) for 5 minutes, remove and cool.
  4. Fry again at 375°F (190°C) until golden and crisp; toss with salt and pimentón.

Jamón-Sherry Reduction:

  1. Sauté shallots in olive oil until translucent.
  2. Add the minced jamón and cook for 1 minute to render fat.
  3. Deglaze with sherry and simmer until reduced by two-thirds into a syrupy consistency.
  4. Strain the solids and reserve the liquid reduction.

Garnish:

  1. Pan-sear the jamón slice until crisp, then break into shards.
  2. Prepare the parsley for a fresh, vibrant contrast.
  3. Combine seasonings for the final dusting.

Tips for Best Results

  1. Ensure the Kennebec potatoes are thoroughly dried after the first boil; excess surface moisture prevents the crust from setting properly.
  2. The reduction is the heart of the dish; cook it slowly until it coats the back of a spoon to ensure a glossy, luxurious finish.
  3. Use a fine-mesh strainer when pouring the reduction over the fries to keep the presentation clean and focused.
  4. For the Basque aesthetic, use a long, dark rectangular plate and place the fries in a neat, architectural stack.
  5. Keep the jamón garnish extremely thin; chilling it slightly before slicing allows for cleaner, more precise pieces.

Plating & Presentation

To achieve the signature Basque aesthetic, utilize a long, dark rectangular plate. Instead of piling the fries randomly, arrange them in a neat, architectural stack. Drizzle the reserved glossy sherry reduction over the top using a fine-mesh strainer to maintain a clean presentation. Finish by placing the shards of crisped jamón vertically against the fries, scattering fresh parsley and the pimentón de la Vera dusting across the stack.

FAQ

Q: Can I use a different potato variety? A: Yes, Russet potatoes are the best substitute for Kennebecs as they share the necessary starch profile. Q: What if I cannot find jamón ibérico? A: Prosciutto serves as a suitable alternative for both the reduction and the crispy garnish. Q: Can I prepare the reduction in advance? A: Yes, you can make the reduction ahead of time, but store it in the refrigerator and reheat gently before serving. Q: Is it possible to bake the fries instead of frying? A: While the triple-cooking method relies on oil for the specific texture, baking will yield different results and will not be as crisp.

Final Thoughts

This dish elevates the humble potato through the meticulous application of traditional Basque techniques and rich, Spanish-inspired ingredients. It invites home cooks to explore the interplay of textures and the depth of a refined reduction. Enjoy the process of crafting this sophisticated plate in your own kitchen.
