Absolutely! Use 4 gelatin sheets to equal 1 envelope of powdered gelatin for this recipe. 1. Place the gelatin sheets in a shallow bowl or rimmed plate. Slowly pour cold water over the sheets, ensuring they don't move around and stick to each other. 2. Allow the sheets to soak for 4-6 minutes until softened. Take the sheets out of the water and squeeze out any excess moisture. Add the sheets to the mango puree and continue with the recipe as written.
