Double-Fried Crispy French Fries

Double-Fried Crispy French Fries rely on a vinegar bath and a two-stage frying process to build a crisp crust around a fluffy center. The initial boiling step activates surface starches. The whole process takes time, but hitting the 400°F (205°C) frying temperature twice creates a rigid golden exterior.

Choosing and cutting potatoes

Select floury and starchy potatoes such as Russet, Sebago, Maris Piper, or King Edward to ensure a fluffy interior and crisp exterior. Waxy potatoes retain too much moisture to crisp up properly. Peel the raw potatoes and slice them into 1/4 inch (6 mm) sticks. Placing two or three potato slices in a stack helps produce uniform baton cuts. Slicing them with a bread knife leaves a textured surface on each piece, which promotes crispier edges.

Keep the cut potatoes submerged in water. The water stops them from turning brown while you finish cutting the remaining pieces.

Rinse the raw cut potatoes in a strainer for 15 to 20 seconds. The running water removes excess surface sugars that cause premature browning during frying.

The boiling stage

Drop the rinsed potatoes into a cooking vessel and cover them with 2 quarts (2 litres) of unheated tap water. Stir in 2 tablespoons of distilled white vinegar and 1 tablespoon of cooking salt or kosher salt. If you prefer, 2 teaspoons of table salt can be swapped for the cooking salt in the water. The distilled white vinegar plays a crucial role by keeping the pieces intact so they do not fall apart during the ten-minute blanching step.

Bring the pot to a boil over high heat, then reduce the stove to low. You want a gentle ripple. A rapid boil will cause the potatoes to break apart. A 10-minute simmer activates the surface starches you need to develop a crisp crust.

Remove the cooked potatoes and spread them across two racks or a clean towel.

Let them steam dry on the counter for 5 minutes. The residual heat dries excess moisture without the need to pat them down.

The first fry

Canola or vegetable oil provides a neutral base suitable for high-heat frying. Pour the oil into a deep pot measuring at least 4 inches (10 cm) high. The liquid should sit 1.2 inches (3 cm) deep. You need 3 inches (7 cm) of clearance at the top to prevent dangerous spillovers.

Heat the oil to 400°F (205°C) over medium high heat. Separate the uncooked potatoes into three batches. A full batch dropped into the hot oil at once causes rapid and hazardous bubbling.

Add one third of the first batch, wait 10 seconds, add another third, wait 10 seconds, and add the rest. Fry the potatoes for 50 seconds. Move the pieces around once or twice.

Take the potatoes out and divide them between two trays lined with paper towels. The fries will look pale and limp right now.

Bring the oil back to 400°F (205°C) and cook the remaining two portions the exact same way. Give the potatoes 30 minutes to cool.

The second fry

Heat the oil once more until it reaches 400°F (205°C). Split the cooled potatoes into two equal halves. Carefully lower one portion into the deep pot and let the pieces cook for 4 minutes.

Move the pieces around two times while they cook until they turn crispy and golden brown. Drain the hot french fries in a large bowl lined with paper towels. A bowl retains heat better than a flat tray while you prepare the second batch. Fry the remaining potatoes the same way.

Seasoning and serving

The boiling water seasons the potatoes internally, so they require less topical salt. Fine table salt or sea salt flakes adhere better to the finished potatoes than large-grained kosher salt. You can apply a Seasoning (choose one) immediately. Options include Table salt or sea salt flakes, Shaker fries seasoning, Rosemary salt, or Nori salt (coming soon). Toss everything well in the bowl and serve the fries right away.

To ensure all the potatoes reach the table hot when making big quantities, drop the completed batches back into the oil together for up to one minute. This brief final dunk reheats everything simultaneously just before serving.

Storing oil and freezing fries

You can cool the frying oil, store it in jars without straining, and reuse it three to four times. You can also freeze the potatoes after the first fry. Cool them completely and freeze them in a single layer before transferring them to an airtight container. You can fry these frozen first-fried potatoes directly from the freezer for four and a half minutes at 400°F (205°C).
