Beer-Battered Onion Rings

READY IN: 1hr 30mins
Recipe by AmyZoe

You probably don't want to know you can make better-than-restaurant quality onion rings in your own kitchen, but these are the best onion rings I've ever had. The recipe is from Cook's Country June/July 2009 from America's Test Kitchens. Make sure you don't soak the onion rounds longer than 2 hours or they will turn soft and become too saturated to crisp properly. Cider vinegar may be used in place of malt vinegar. Use a candy thermometer to make sure the oil gets to 350 degrees. According to Cook's Country, ordinary yellow onions will produce acceptable rings but sweet onions are preferred. The beer soaking with vinegar and salt softens and flavors the raw onion. If the batter is too thick, the rings will be doughy. Too thin, and it will run off. Add the beer gradually until the batter falls from the whisk to form a ribbon trail. Fry the battered onion rings in small batches and transfer them one at a time to the hot oil so they don't stick together.

This recipe was featured in America's Test Kitchen Best Recipes And Reviews 2010 and it was my first attempt at making onion rings at home. It really was not difficult and I was very pleased with the results - the onions were tender and the beer did add a lot of flavor. I did make one observation - make sure you do cut your onions 1/2" thick. Some of mine were not that thick (only by accident) and I found it made a noticeable difference - the thicker ones were much better. The onion kind of got lost in the thinner ones. The original recipe did state to use an ale or lager beer such as Bass or Samuel Adams and you will need two 12-Ounce beers. I bought the Samuel Adams, but unfortunately (or not) I had to buy a six-pack so I will be forced to make these again to use up the rest of the beer - darn that bad luck!
