Minecraft wiki entry for Hardcore_mode, associated text: Nether Survival: If there are no nether fortresses nearby, you may be forced to spend a lot of time in the Nether. Food supplies can be easily replenished, using very abundant mushrooms, or killing Hoglins which drop porkchops. Use torches or distinctive nonflammable blocks, like cobblestone, dirt or crafting tables to mark the path back to the portal.
