Prepare the Pork and Vegetables: Heat a skillet over medium heat and add a dollop of oil. Add the crushed garlic and grated ginger, frying until fragrant. Slice the pork neck into cubes and add to the skillet, cooking until browned. Add the cooked corn, sautéed mushrooms, and diced spring onions.
Add the Rice: Scoop in the cooked sushi rice and sesame seeds. Season with salt and black pepper, then reduce the heat to low.
Make the Sticky Sauce: In a bowl, mix the soy sauce, honey, ketchup, rice wine vinegar, and sesame oil. Pour the sauce over the rice mixture and stir well. Let it simmer for another three minutes before removing from the heat.
