Join Claire Saffitz in the Bon Appétit Test Kitchen as she attempts to make gourmet Thin Mints, Samoas and Tagalongs. That's right, Claire's making Girl Scout Cookies. Did you know the Girl Scouts started selling cookies back in 1917? But it wasn't until 1951 that the Thin Mint, the cookie most synonymous with the Girl Scouts, was introduced and swept the country like a tidal wave. And now here we are, in the Test Kitchen, watching Claire make them herself. What a time to be alive.
