Can I use other vinegars besides apple cider?

Absolutely, While apple cider vinegar is my personal favorite, malt vinegar gives that classic British chip shop flavor. White wine vinegar works beautifully too - it's a bit more subtle. I'd avoid balsamic unless you want sweeter chips (though that can be delicious too). Just stick to the same 1 tablespoon measurement.

Why did my kale chips turn out soggy?

Oh no, This is usually one of three problems: 1) The kale wasn't dry enough before baking (water = soggy chips), 2) The baking sheet was overcrowded (they need space to crisp up), or 3) They didn't cool completely before storing. Next time, really dry those leaves, use two baking sheets if needed, and let them cool fully before digging in.

Can I make these in an air fryer?

You bet, I do this all the time when I want a small batch fast. Cook at 300°F for about 8-10 minutes, shaking the basket halfway. They cook faster in the air fryer, so check often to prevent burning. The chips come out extra crispy this way.
