Whipped Berry Pudding

Combine water and blueberries in a medium saucepan and bring to a boil over medium-high heat. Simmer, uncovered, for 15 minutes. Strain the blueberries, pressing on the solids; you will have 3 to 3 1/2 cups blueberry juice. (Discard the solids.)

Rinse the saucepan and return the juice to it. Stir in farina, sugar, lemon juice and salt. Cook over medium-low heat, stirring, until the mixture has thickened slightly, 2 to 4 minutes. Remove from the heat and let cool for 15 minutes.

Transfer the farina mixture to a stand mixer and beat with the whisk attachment on low speed for 1 minute. Increase speed to high and beat until doubled in volume, with a texture similar to fluffy marshmallow, 8 to 10 minutes more.

Refrigerate until chilled, about 2 hours. Serve garnished with blueberries, if desired.
