Place julienned carrots in a large mixing bowl. Add salt and sugar, toss, and let sit for 15–20 minutes to soften. Add minced garlic, ground coriander, black pepper, vinegar, and soy sauce to the carrots
In a small skillet, heat vegetable oil until very hot but not smoking. Carefully pour hot oil over the garlic and spice mixture in the bowl to release the aromas. Sprinkle in chili flakes and sesame seeds. Mix everything thoroughly
Cover and refrigerate for at least 1 hour to let flavors develop. Stir before serving and garnish with chopped cilantro. Serve chilled and enjoy!
