Aromatic fresh ginger lends its signature flavor to these inspired frozen cocktails, a celebration of the juicy, succulent peach. When buying peaches, look for intensely fragrant fruit that gives slightly to palm pressure. Avoid those with signs of greening.
Place pureed peaches, ginger syrup, lime juice and peach juice or nectar in a blender and mix together. Pour the mixture into a bowl and place in the freezer. When ready to serve, add tequila and Cointreau. Combine well and serve with lime slices. Makes 8 generous margaritas.
