There are two methods to grind your salt into a finer texture, which makes it perfect for adhering to buttery popcorn. The first method is mortar and pestle, and this is our preferred method. The second is a food processor or high-powered blender.
Mortar and pestle method: Place the salt in the mortar (the bowl) and crush the salt using the pestle. Once the salt begins to break down, start moving in circles to grind it as fine as you can.
Food processor method: Place the salt in the food processor and blend on high until the salt becomes fine (you will know this has started as salt dust rises in the food processor). A mini food processor works better for this, or you can make a larger batch in a full-size model. Keep blending until it is very fine (this can take longer than expected). Flaky salt (like Maldon) will blend to a powder more easily, while fine table salt does not appear to have changed much (on closer inspection you will notice that it has).
Serve with popcorn. Sprinkle your homemade popcorn salt on buttered hot popcorn, then toss and adjust according to your taste. We love Maldon salt for this, or using specialty salts like smoked salt or herb salts. It elevates your homemade popcorn to the next level.
Notes
We recommend using this recipe along with our best ever homemade popcorn and clarified popcorn butter. It’s a winning trio and you will not regret it!Type of salt and method: Fine granular table salt or sea salt is harder to grind to a fine powder, while flaky salt like Maldon is easier. We also prefer the mortar and pestle method to the food processor for textural reasons, as it grinds the salt more finely. Storage: Transfer any leftover salt to a small airtight container. Store at room temperature for an indefinite amount of time. You may notice it will clump during periods of high humidity or moisture, but you can break it apart easily and re-grind if necessary.Flavored salts: It’s easy to make delicious flavored popcorn salt by using specialty salt and grinding it fine in a mortar and pestle or food processor.
