You don’t need a copper kettle to nail this at home. You just need a heavy-bottomed pot (a Dutch oven works perfectly), some coconut oil (it has a high smoke point and adds subtle sweetness), and fine, superfine sugar. Regular granulated sugar works, but superfine dissolves faster and reduces bitterness.

Here is the pro move: swirl, don’t stir. When you add the sugar to the hot oil, swirl the pot gently to distribute it. Aggressive stirring can crack the kernels or create sugar clumps. And for the love of good snacks, taste a piece before salting—the sugar may be enough, especially if you used salted oil.
For the ultimate hack, try the half-batch method. Pop half your kernels, then add the sugar and the rest of the kernels. This ensures the sugar caramelizes without scorching the first batch. The result is a deeper, more complex flavor that tastes like a state fair in your living room.
