Recipe from chowmama.com.
I substituted rice vinegar for apple cider vinegar and used 1/2 teaspoon fine sea salt and the chips were a bit too salty. Mine became crispy only after 20+ minutes in 400 degrees oven.
They disappeared so fast I might have to make multiple batches next time. I wonder if they will stay crisp for a few days. If I have these on hand whenever I crave salty snacks, I will be the healthiest snacker ever!
