Past tense of 'to cook'. This is the adobo your mom made, the sinigang you miss from home, or the instant noodles you "cooked" at 2 AM. It can also be used figuratively for anything that's been "cooked up" or manipulated, like "nilutong eleksyon" (rigged election) or "nilutong laban" (a fixed match). The most important question at any Filipino gathering: "Sino'ng nagluto nito?"
