Onion Rings

Method

1. brine30 min
   thick rings in buttermilk
   the separated rings submerged — the soak softens the raw sulfur bite and leaves a tacky film the flour dust will anchor to; the two inner-most tiny rings go to the chopping board for another day, as every fry cook learns
2. whisk3 min
   batter at the last minute: flour + cornstarch + powder + beer
   1 cup flour + cornstarch + baking powder + 1 tsp salt + paprika + the cold beer, lumps welcome — the fish-and-chips batter doing its second job; mixed only when the oil is already at temperature, because the bubbles are the crunch and they are leaving from the moment the whisk stops
3. fry15 min
   365°F, dusted then dipped, 4-5 rings a batch, ~2.5 min
   each ring from the buttermilk through the reserved dusting flour, then the batter, then straight down into the oil — turned once at golden, racked never papered; the dust-batter sequence is the anti-slip engineering: the crust bonds to the onion instead of merely surrounding it
4. season2 min
   salted the instant they land
   the remaining salt while the rings still glisten — the hot-crust salt law from the tenders entry, universal across the fried chapter; eaten within ten minutes, stacked beside a burger, or alone as the dinner nobody planned and nobody regrets
