I never met a French-fried onion ring I didn't like. Alas, some more than others. Witness these rings from the Tasty Burger in Harvard Square. Below average. Too crinkly, the batter breaking and falling off the onion. (That, of course, did not prevent me from eating every last crumb.) Fortunately the superb company for this dinner out more than made up for any shortcomings in the rings department.
