The host of "Top Chef" and "Taste the Nation" has sampled--and judged--dishes from around the country and the world. How did she develop her discerning palate? Padma Lakshmi is unquestionably a woman of taste. As a host of the beloved food-competition series "Top Chef" and the star of the culinary docuseries "Taste the Nation," she's spent nearly two decades artfully conveying--and critiquing--flavors and aromas for an audience. Before that, she was a fashion writer and model, cultivating her own sense of what's worth wearing and seeing. And she isn't done evolving: she's recently begun performing standup comedy, an art form with a notoriously steep learning curve.
