Spicy Spinach Dip with Pine Nuts

Scoop the yogurt into a paper towel-lined strainer set over a bowl. Let stand at room temperature for 30 minutes. You should end up with a 1/2 cup yogurt. Meanwhile, heat the olive oil in a small skillet. Add the pine nuts and minced onion and cook over high heat, stirring frequently, until the onion is softened and lightly browned and the pine nuts are golden, 4 to 5 minutes. Add the cumin, coriander, chile powder and cayenne and cook, stirring, for 1 minute. Scrape into a bowl. Using your hands or a potato ricer, squeeze the spinach until very dry, then coarsely chop it and discard any stringy pieces. Stir the spinach and yogurt into the onion mixture and season with salt.
