In Mexico the rosella, also known as the wild hibiscus flower, is referred to as the flor de Jamaica. The growing interest in foraged foods has reminded us that there are so many new and interesting wild foods. The Australian riberry, also known as lilly pilly, is one of these. Red currants would make a great substitute. This refreshing aperitif is a great way to start an evening. Made with blanco tequila, homemade rosella tea and crowned with Champagne and native berries, this is the perfect summer drink!
