The Strategic Slice
Cut your sweet potatoes into uniform 1/4-inch fries. This size is the "Goldilocks" of fry cutting—thick enough to feel substantial, but thin enough to crisp up without burning.
The "Starch-Release" Soak
The Secret Step: Place your cut fries in a bowl of cold water for 20 minutes while your oven preheats. This draws out excess surface starch. After 20 minutes, drain them and pat them dry—I mean really dry. Moisture is the enemy of the crunch.
Seasoning and Spreading
Toss the dried fries in a large mixing bowl with the olive oil, sea salt, and smoked paprika. Once every fry is lacquered in spice, spread them on a rimmed baking sheet.
Critical Rule: Do not overlap the fries. If they touch, they will steam. Give them space to breathe so they can roast.
The Roast
Bake at high heat, flipping them halfway through. You are looking for deep orange centers and slightly charred, caramelized tips.
Prepping the "Pollock" Sauce
While the fries roast, mix your vegan sour cream with lime juice. If it’s too thick to drizzle, add a teaspoon of water. Dice your avocado and toss it immediately with lime juice to lock in that vibrant green color.
The Grand Assembly
The moment the fries exit the oven, the clock starts. Pile the black beans on first (the residual heat from the fries will warm them). Follow with the avocado, red onion, and cilantro. Finally, take your lime cream and zigzag it over the top like a piece of edible modern art.
