I love playing with jamaica, or hibiscus, flowers in my kitchen. 🌺 They can add a refreshing tart, acidic flavor to many things like drinks, sauces, vinaigrettes, and desserts. I found a way to use the rehydrated jamaica flowers, which typically are discarded after simmering, in these fudgy dark chocolate cookies. They make a great chewy, tangy addition that's a little like cranberry.
