Anyway you fry it, America loves donuts, and these three shops are a cut above the rest. There are vegan delights at Donut Friend in Los Angeles, with everything from berries and mint to donut sandwiches; at Underwest Donuts in New York, they prove you can have your Halva Tahini donut and eat it too; In Honolulu, Champion Malasadas serve up Portuguese-style donuts fried to order and covered in sugar.
