2 cups brine from Cauliflower-Heart Pickles or other jarred pickles
3 garlic cloves
3 tablespoons fresh lemon juice
3/4 teaspoon kosher salt
1/2 cup tahini
Pinch of ground cumin
1/4 cup harissa
Canola oil
for frying
Instructions
In a medium bowl, cover the sliced potatoes with the pickle brine and refrigerate overnight.
In a food processor, combine the garlic, lemon juice and salt and pulse until a coarse puree forms.
Let stand for 10 minutes.
Strain through a fine sieve set over a small bowl.
Stir in the tahini, cumin and 3 tablespoons of water until smooth, then stir in the harissa and 1/2 tablespoon of the pickle brine.
Season with salt.
Drain the potatoes and pat dry with paper towels.
In a nonstick skillet, heat a thin layer of oil.
Working in batches, fry the potatoes in a single layer over moderately high heat, turning occasionally, until theyre lightly browned and tender, about 5 minutes per batch.
