Shredded Sweet Potato and Carrot Fritters (Ukoy)

Preparation

1. Chile Vinegar:

   Step 1

   Mix chiles, garlic, onion, and vinegar in a small bowl; season with salt.

2. Fritters:

   Step 2

   Thinly slice sweet potatoes and carrots into 3x1/4" planks (use a mandoline if you have one), then slice lengthwise into matchsticks. Place in a medium bowl and toss with a few pinches of salt. Let sit until slightly softened, about 30 minutes. Rinse off salt and pat dry.

   Step 3

   Pour oil into a large heavy pot to a depth of at least 2" but with at least a 4" headspace, as oil will bubble aggressively when you add fritters. Fit pot with thermometer; heat oil over medium-high until thermometer registers 330°F–340°F.

   Step 4

   Meanwhile, combine club soda and fish sauce in a large measuring glass. Add cornstarch and whisk until smooth. Place half of sweet potato and carrot mixture, shrimp, and cilantro in a medium bowl and toss to combine. Pour in half of cornstarch slurry and toss to coat (slurry should cling to shrimp and vegetables in a light, even layer).

   Step 5

   Using a slotted spoon, carefully lower half of slurry-coated vegetable and shrimp mixture into oil. Once bubbling subsides, mixture will disperse across the surface of oil. Using a spider or a clean slotted spoon, corral vegetables and shrimp by gathering them against the side of the pot until they form a large mound that clings together and can be turned as a single unit. Fry, turning occasionally and increasing heat as needed to keep oil temperature between 330°F and 340°F, until fritter is golden brown and crisp around edges, about 4 minutes. Transfer to a wire rack set inside a rimmed baking sheet. Repeat process with remaining slurry-coated vegetable and shrimp mixture, adding a splash or so of club soda if needed to loosen batter (it should look like a glossy coating), to make another fritter.

   Step 6

   Repeat entire process with remaining sweet potato and carrot mixture, cilantro, shrimp, and cornstarch slurry to make 2 more fritters.

   Step 7

   Season fritters lightly with salt. Serve with chile vinegar alongside for dipping.

3. Do Ahead
