We’ll be spreading membrillo (quince paste) inside bread for grilled cheese from now on. This recipe is from Morcilla, one of Bon Appétit's Hot 10, America's Best New Restaurants 2016.
Ingredients
8 ounces membrillo (quince paste)
2 tablespoons sherry vinegar
1 tablespoon Aleppo-style pepper
1 teaspoon fresh lemon juice
1 cup all-purpose flour, plus more for hands
8 ounces chilled fresh goat cheese
1 1/2 cups panko (Japanese breadcrumbs)
2 large eggs
Vegetable oil (for frying; about 6 cups)
Kosher salt
A deep-fry thermometer
Directions
Pulse membrillo, vinegar, Aleppo-style pepper, and lemon juice in a food processor until smooth. Transfer to a small bowl.
Using floured hands, form a heaping tablespoonful of goat cheese into a 1 1/2"-long log. Transfer to a parchment-lined baking sheet. Repeat with remaining cheese to make 15 more logs. Chill until firm, about 20 minutes.
Pulse panko in a food processor until very finely ground; transfer to a shallow bowl. Whisk eggs and 1 Tbsp. cold water in a second shallow bowl. Place remaining 1 cup flour in a third shallow bowl. Dredge a log of goat cheese in flour, shaking off excess. Dip in egg mixture, letting excess drip back into bowl, then coat in panko, pressing to adhere. Repeat process to create a second coating. Transfer to a baking sheet. Repeat with remaining logs of goat cheese. Chill croquettes in freezer until firm but not frozen solid, about 15 minutes.
Pour oil into a large heavy pot to come 2" up sides. Fit pot with thermometer and heat oil over medium-high until thermometer registers 350°F. Working in several batches to avoid crowding the pan, fry croquettes, turning occasionally, until golden and crisp, about 2 minutes. Transfer to paper towels to drain; season with salt.
