Guanabana Caramel Flan Recipe

Living in Costa Rica gives us access to great fruits and vegetables that you would never find anywhere else. One of those fruits grows in abundance at Blue Osa – guanabana also known as soursop. We are so fortunate to have an abundance of fresh and interesting produce readily available at our fingertips. Guanabana is famed for its cancer fighting properties.
