# Components:
→ Blackcurrant Purée
01 - 2/3 cup blackcurrant purée (fresh or frozen blackcurrants, blended and strained)
02 - 2 tablespoons water
03 - 2 tablespoons granulated sugar
→ Marshmallow Base
04 - 3 packets (21 g) powdered unflavored gelatin
05 - 1/2 cup cold water
06 - 1 1/2 cups granulated sugar
07 - 1/2 cup light corn syrup
08 - 1/4 cup water
09 - 1/4 teaspoon salt
10 - 1 teaspoon vanilla extract
→ For Dusting
11 - 1/2 cup confectioners sugar
12 - 1/4 cup cornstarch
# Method:
01 - Line an 8x8 inch baking pan with parchment paper and lightly dust with a mixture of confectioners sugar and cornstarch.
02 - In a small saucepan, combine blackcurrant purée, 2 tablespoons water, and 2 tablespoons sugar. Simmer over medium heat for 4–5 minutes, stirring until slightly thickened. Transfer to a bowl and cool to room temperature.
03 - In the bowl of a stand mixer, sprinkle gelatin over 1/2 cup cold water and let bloom undisturbed for 10 minutes.
04 - In a medium saucepan, combine 1 1/2 cups sugar, corn syrup, and 1/4 cup water. Heat over medium-high heat, stirring until sugar completely dissolves. Insert a candy thermometer and continue cooking without stirring until the syrup reaches 240°F.
05 - With the stand mixer running on low speed, carefully pour the hot syrup into the gelatin mixture. Increase speed to high and whip for 6–8 minutes, until the mixture becomes thick, glossy, and has tripled in volume.
06 - Add salt, vanilla extract, and cooled blackcurrant purée to the whipped mixture. Continue whipping for 1–2 minutes until fully incorporated and the mixture achieves a soft lavender color.
07 - Immediately pour the marshmallow mixture into the prepared pan and smooth the top with a spatula. Sift a generous layer of the confectioners sugar-cornstarch mixture over the top. Leave uncovered at room temperature for at least 4 hours until completely set.
08 - Turn the marshmallow slab onto a cutting board and peel away parchment paper. Dust all sides with the sugar-cornstarch mixture. Cut into squares using a sharp knife dusted with the same mixture.
09 - Place finished marshmallows in an airtight container. Store at room temperature for up to 1 week.
