Why mess with a good thing? The easiest answer is probably: “Because it’s fun.” Another legitimate reason to mess with a fast food staple like onion rings is because some people can’t enjoy normal onion rings. Yes, let’s not forget that those with gluten allergies and intolerances are denied the pleasure of the crunchy, battered, salty-and-almost-kinda-sweet snack.  That’s why Chris Kronner of Kronnerburger in San Francisco decided to update this classic dish. By swapping wheat flour and beer with rice flour and sparkling water, you have an extra crispy and delicious snack that can be enjoyed by all. RECIPE: Gluten-Free Onion Rings But be warned: Like their gluten-laden counterparts, they’re still addictive as hell.
