First, the star of the show: onions. You want big, sturdy yellow or white ones. Red onions are pretty, but they get a bit weepy and soggy. We want warriors, not poets.
Next, a big bowl of cold water. This isn’t a swim lesson; it’s a secret hack to make your onions extra crunchy. Trust the process.
Finally, you need flour (all-purpose is perfect), salt, a little pepper, and a pot of neutral oil for frying. Vegetable or canola oil works like a dream. Save your fancy olive oil for dipping bread; it’ll just burn and get mad at you.
