How to Make It
Preheat the oven to 350° and line a baking sheet with parchment paper. In a large saucepan, combine the vegetable oil and popcorn, cover and cook over moderate heat until the corn starts to pop. Cook, shaking the pan until the popping stops, 3 to 5 minutes. Transfer the popcorn to a large bowl and season lightly with salt.
Wipe out the saucepan. Add the olive oil, sugar, sesame seeds, soy sauce, garlic powder and 2 teaspoons of salt and cook over moderate heat, stirring, until the sugar dissolves, about 3 minutes. Add the pistachios and cook, stirring, for 1 minute. Scrape the pistachios onto the prepared baking sheet and bake for about 10 minutes, until bubbling. Scrape the pistachio mixture into the popcorn and toss well. Let cool before serving.
