Chicken Tostadas with Radish Slaw
Time: 90 minutes
fresh orange juice, 2/3 cup (5 fl oz/150 ml)
fresh lime juice, 3 tbsp
achiote paste, 3 tbsp
yellow onion, 1 small, chopped
garlic, 2 cloves, chopped
dried oregano, 1/2 tsp
boneless, skinless chicken thighs, 2 lb (1 kg)
kosher salt and freshly ground pepper
FOR RADISH SLAW
radishes, 2 cups trimmed, halved, and thinly sliced
green onions, 2, thinly sliced
fresh cilantro, 1/3 cup (1/2 oz/15 g) chopped
fresh lime juice, 1 tbsp
corn oil, for frying
corn tortillas, 12, each 4 inches (10 cm) in diameter
cotija cheese, 3 oz (90 g), crumbled
avocados, 2 large, halved, pitted, peeled, and sliced
Prepare the chicken, in a heavy Dutch oven, stir together the orange juice, lime juice, and paste until the paste is smooth. Add the onion, garlic, and oregano and mix well. Add the chicken thighs and turn to coat evenly. Sprinkle the chicken with salt.
Cover, place over medium heat, bring to a simmer, then reduce the heat to low and cook, stirring occasionally, until the sauce has thickened and the chicken is opaque throughout when pierced with a knife tip, about 40 minutes. Uncover and continue to simmer until the sauce is very thick and the chicken begins to fall apart and catch on the bottom of the pan, about 10 minutes.
Remove from the heat and let cool slightly, then shred the chicken. Season with salt and pepper.
To make the radish slaw, in a small bowl, combine the radishes, green onions, cilantro, and lime juice and toss to mix. Season with salt.
Pour oil to a depth of 1 inch (2.5 cm) into a deep, heavy frying pan and warm over medium-high heat until almost smoking. One at a time, add the tortillas and cook, turning once with tongs, until crisp and golden, 1-2 minutes. As each tortilla is ready, transfer it to paper towels to drain, then sprinkle lightly with salt.
