# How-To Steps:
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. Set aside to cool to room temperature
03 - In the bowl of a stand mixer, sprinkle gelatin over 1/2 cup cold water and let bloom 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, stirring until sugar dissolves. Insert a candy thermometer and cook without stirring until the syrup reaches 240°F
05 - With the mixer running on low, carefully pour the hot syrup into the gelatin mixture. Increase speed to high and whip for 6–8 minutes, until thick, glossy, and tripled in volume
06 - Add salt, vanilla extract, and cooled blackcurrant purée. Whip another 1–2 minutes until fully incorporated and the mixture reaches a soft lavender color
07 - Immediately pour the marshmallow mixture into the prepared pan, smoothing the top with a spatula. Sift a generous layer of the confectioners sugar-cornstarch mixture over the top. Let sit uncovered at room temperature for at least 4 hours or until fully set
08 - Turn the marshmallow slab onto a cutting board, peel away parchment, and dust all sides with the sugar-cornstarch mix. Cut into squares with a sharp knife dusted in the same mixture
09 - Store in an airtight container for up to 1 week
