Storage: Sushi rice is best served at room temperature. Cover with a moist towel to prevent drying out. Do not refrigerate sushi rice as it will harden.
Food Safety: If using raw fish, ensure it is sushi-grade. For safety against parasites, freeze fish slices for at least 24 hours before using, then thaw.
Variations: Common fillings include fresh tuna, salmon, avocado, pickled daikon, and fried tofu. For Umekyu, add a small amount of umeboshi paste to the filling.
Serving: Serve sushi with fresh wasabi, pickled ginger (gari), and soy sauce. Traditionally, dip the fish side of nigiri into soy sauce, not the rice, to prevent the rice from falling apart.
Technique: Keep a bowl of water with a splash of vinegar nearby to wet your fingers while handling rice to prevent sticking.
