A delicate sprinkle of caster sugar can transform a straightforward meringue into a refined masterpiece, as I love in my Strawberry Blackberry Pavlova. It’s the secret behind the light, crisp exterior of my Tropical Fruits Pavlova, adding just the right touch of sweetness. For a decadent finish, I often use it to elevate the richness of my Chocolate Hazelnut Pavlova, proving that even the simplest ingredient can carry a gourmet punch.
