Avoid melting or damaging your work surface with the heat from the iron by placing the sandwich onto a baking sheet. Put 1-2 pot holders underneath the baking sheet to keep it from slipping if needed. Instead of a baking sheet, use a heat-resistant cutting board. These are typically made out of stone or wood and can be purchased in the kitchen section of your local department store or online with major retailers. Make sure to place the hot iron back onto a heat-resistant surface to avoid damaging your work surface. Allow the iron to cool off completely before storing it. Be careful as you unwrap the sandwich, as the steam trapped within the foil will be hot. Place your grilled cheese sandwich onto a serving plate, and enjoy!  Use your butter knife to cut the sandwich in half to make it easier to eat. Repeat the cooking process as needed for any additional sandwiches. As long as the foil does not have any holes in it, reuse the same piece of foil to make multiple sandwiches.

One-sentence summary -- Set the wrapped sandwich onto a baking sheet to protect your work surface. Remove the iron and turn it off when your sandwich is finished cooking. Let the sandwich rest for 1-2 minutes before unwrapping and serving it.


Many movie theaters use salt processed using the Alberger process, as the many jagged edges on the salt crystals help it stick to the popcorn. Diamond Crystal is the only consumer salt brand in the United States that uses this process. You can get a similar effect from extra-fine powdered salt, which is often sold as "popcorn salt" and stocked next to the popcorn. You can create powdered salt at home by grinding any salt in an electric coffee grinder, hand-turned salt mill, or mortar and pestle. If using a coffee grinder, grind a small amount of coffee beans afterward to remove the leftover salt. . Theaters that do use real butter (rather than butter-flavored oil) often use clarified butter. Clarification removes some moisture from the butter, which prevents the popcorn becoming soggy. You can clarify butter at home just by melting it over low heat until the bubbling stops and the liquid turns clear, about 30-40 minutes for 1 lb (0.45 kg) of butter. Strain the liquid through a damp cheesecloth and let cool to make clarified butter. Discard the milk solids left in the cheesecloth or at the bottom of the pan. The famous "buttered popcorn" smell of a movie theater comes from artificial butter flavor. Actual butter won't replicate this perfectly. You may want to save the clarified butter for later drizzling, as it will likely brown or burn if you try to pop kernels in it. Coconut oil used to be the standard in movie theaters (and many still use it), but you may wish to follow a more recent trend and switch to canola oil, which has less saturated fat and a higher smoking point. Whichever you choose, pour just enough oil to cover the base of a large pan. Heat on a stovetop until the oil shimmers.  Note that most theaters that use canola oil actually use a more hydrogenated version that contains more fat than consumer canola oil. If using coconut oil, the oil should melt completely. You'll need a pan with a lid, but you do not need to cover it now. . Throw in a few unpopped kernels and cover the pot. Once these kernels have popped, add the rest of the popcorn. Use ⅓ cup (80 mL) popcorn kernels for a 6 quart (5.6 L) pot. Cover and heat, shaking occasionally, until most of the kernels are popped. Pour popped corn into a large bowl whenever the pot gets full.  Leave the lid slightly ajar so some of the steam escapes, preventing soggy popcorn. To reduce the number of burned or unpopped kernels, remove from heat right after adding the kernels. Wait for thirty seconds so the kernels reach an even temperature, then return to heat. You'll need about ⅓ tsp (1.5 mL) of fine grained salt in this recipe. The exact size of the salt crystals affects the flavor, so you may need to adjust to taste. Add the salt right after the popcorn is popped, since the steam clinging to the popcorn will help the salt stick. Pour the popcorn into a large bowl. Add 1 or 2 tbsp (15–30 mL) room temperature clarified butter to the hot pan, according to taste. It should melt quickly in the hot pan without additional heat. Drizzle it onto the popcorn when the butter is still yellow or only slightly brown.
