Instructions Checklist
  • Sprinkle gelatin over cold water in a small bowl; let stand until softened, about 5 minutes.

  • Heat cream, sugar, and salt in a small saucepan over medium heat, stirring to dissolve sugar and salt. Add gelatin mixture and stir until it has dissolved. Remove from heat; let cool. Stir in buttermilk and lemon juice.

  • Remove crust from pan. Spread filling into crust and refrigerate until slightly set, about 15 minutes. Scatter blueberries evenly over top. Refrigerate until filling is firm, about 2 hours (or up to 1 day).
