In celebration of the opening of Sausalito’s new Copita, a joint venture of restaurant veteran Larry Mindel and chef and cookbook writer Joanne Weir, we decided to share a recipe for the perfect margarita. A longtime resident of Sausalito, Mindel has wanted to open an authentic Mexican restaurant offering seasonal dishes and fresh produce from his garden for many years. After he tasted one of Weir’s “perfect” margaritas, plans were set in motion to open a restaurant together. Weir, who previously cooked at Chez Panisse, is a James Beard Award–winning cookbook author and the host of Joanne Weir’s Cooking Confidence on PBS. The word copita refers to a small glass used to taste tequila — seems like the right moniker for their new place.
