Versions of this recipe/application appear in various places. This is the version that looks most appealing to me, though I’ll admit I haven’t tried it yet. Not for lack of kale, though, or even lack of interest… it just keeps slipping my mind! Maybe now that I’ve put it here, I’ll remember.
3 or 4 large kale leaves, with stem removed and cut into 2″ pieces
2 tbsp apple cider vinegar
1 tbsp extra-virgin olive oil
A few pinches of kosher salt
Preheat oven to 350 and line a baking sheet with parchment paper. Whisk together vinegar, oil, and salt, and toss with kale leaves. Place in a single layer on sheet and place into oven. Bake 10-15 minutes, flipping halfway through until crispy. When kale gets brown, it gets very bitter- – so pull them out before then!
