Crispiest onion rings.
Here's how to make the crispiest onion rings! The trick is an ice-cold seltzer batter that puffs up light and crackly in the oil — way better than anything from a drive-thru. Two Osmo salts do the work here: Osmo Roasted Garlic Salt goes straight into the batter, and Osmo Flakey White Sea Salt gets tossed on the rings the second they come out of the fryer.

Step 07
Dredge and dip in batter
Dredge each ring in plain flour, dip it in the batter, then drop it straight into the oil. That first coat of flour is what helps the batter grab on.
