I really like popcorn. I often find myself watching TV just as an excuse to eat popcorn. I've gone months where I had it every night. A while ago I decided to buy an air popper. I've built up quite a recipe around the air popper, and I'd like to outline it here.
Why an air popper?
Air poppers are like $20 and the popcorn is much cheaper than the microwave bags. They are a bit faster than a microwave, and you can never burn it. There is nothing to clean because you only put dry popcorn in them, the oil is added afterwards.
Air Popper
I did a fair bit of research into air poppers, as I tend to do before buying anything. Long story short, they're all the same, and you should get a cheap one. This one is about $20. It has a built in measuring cup, you dump the dry kernels in the top, and plug it in. Set a large bowl next to it, and wait a few minutes. The last 10 or so kernels never pop, so give up on them. Unplug and that's it.
Kernels
A few people recommended Orville Redenbacher for air poppers. I started out buying at the grocery store, but you can get a giant jug on Amazon for cheap.
Bowl
It sounds silly, but you do need a large bowl. I always ate popcorn straight from the bag, so I didn't have one. I just got a 7 L one from Walmart. Make sure it's at least 6 liters.
Salt
You can just use regular salt, but finer salt will stick better. Generally you'll waste tons of salt no matter what. After much research I found this movie theater style salt which is great, and will last like 30 or so bowls.
Salt Shaker
You can just use any regular shaker. But I'm generally looking for one that has a few, well-separated, smaller holes. The popcorn salt is much finer, so it comes out very fast of normal sized holes. This is the best I've found so far, it works, but the holes could be a bit smaller.
Oil
You need oil, basically to make the salt stick. I've just been buying this generic popcorn oil. Don't expect much flavor from the oil, it's basically just soybean oil. I've heard coconut oil is the best flavor, but it's difficult to spray on.
Sprayer
It's basically impossible to drizzle oil evenly. I bought this spray bottle, which is crazy expensive, but is designed for oil. There are cheaper oil sprayers but the reviews say they clogged, whereas I've been using this one for months and it's fine. A word of warning, they spray in a flat fan pattern, which means you have to move the sprayer as you spray.
