Start by popping your popcorn kernels. You can do this your preferred way i.e. air popper, stove top, microwave, etc, or I'll explain below how I do it on the stove top.
Heat a medium saucepan (that has a lid) to medium high heat and add the avocado oil. Once it heats up for a minute, tilt and turn the pan so that the oil spreads evenly on the bottom of the pan.
Sprinkle the popcorn kernels in a single even layer over the bottom of the pan.
Cover the saucepan and leave it alone until the kernels start to pop.
While you're waiting for the kernels to pop, you can get your seasoning ready. Do this by adding all of the seasoning ingredients, from almond flour to lemon juice to a mixing bowl or food processor.
I like to blitz my mixture in a food processor or blender, but you can just mix it by hand in a bowl. Also, the lemon juice can be optional, but I like the little lift in flavor it gives!
Once the kernels start to pop, carefully lift and shake the pan (wearing oven mitts and holding the lid down) every 30 seconds to 1 minute to make sure the unpopped kernels stay at the bottom.
Once the popping has died down and there's a few seconds between each "pop", turn the heat off and immediately transfer the popcorn to a large bowl.
Drizzle some avocado oil over the popcorn (or melted butter, ghee, olive oil, etc.) and then toss the seasoning in the bowl. Either cover the bowl and shake it to coat the popcorn, or stir it gently with a large spoon or spatula.
Give it a taste and add more salt, as desired. Enjoy!
