Ingredients
Flavor options (choose 1)
Classic: 2 tablespoons dried chile flakes
Bright, nutty red: 1 ½ tablespoons dried chile flakes + 1 ½ teaspoons Korean coarsely ground chilegochugaru + 1 tablespoon sesame seeds
Zingy: 1 tablespoon dried chile flakes +1 ½ teaspoon Korean ground chile (gochugaru) + 1 ½ teaspoon ground Sichuan peppercorn
Citrusy: 1 ½ tablespoons dried chile flakes + 1 ½ teaspoons Korean ground chile (gochugaru) + peel of 1 navel orange (use a vegetable peeler to remove)
Oil options (choose 1)
Asian market: ½ cup (120ml) semi-refined peanut oil(see Note)
Toasted peanut-y hack: ⅓ cup (80ml) unrefined toasted peanut oil + 2 ½ tablespoons neutral oil
Ready the vessel: Put the chile flakes and any other seasoning(s) in a dry glass jar (1 cup capacity is what I used)or small metal bowl.
Make the oil: Put the oil(s) in a small saucepan. Heat over medium heat until smoking hot (the temperature will top 400°F) and remove from the heat. Wait 3 to 4 minutes for the temperature to decrease to 325° to 350°F (drop a chile flake in and it should gently sizzle), and then carefully pour the oil into the glass jar. The chile flakes will sizzle and swirl. Cool completely before covering and storing up to several months; refrigerate if to keep for longer. Regardless, let the oil mature for 24 to 48 hours before using.
Notes
For the semi-refined peanut oil, Lion and Globe brand sold at Chinese markets is the standard and very good.
Unrefined roasted peanut oil is available at health food grocers. Whole Foods, Spectrum, La Tourangelle have lots of peanutty flavor.
