Prepare silicone molds or a silicone cake pan (9x9) on a cookie sheet on a heat-proof surface. Alternatively, line a baking pan with parchment paper.

In a medium heavy-bottomed saucepan, combine strawberry puree, sugar, and corn syrup. Set over medium to medium-high heat and bring to a boil.
03 -
In a small saucepan, combine pectin, baking soda, and water. Simmer over medium-high heat, stirring occasionally, until foam subsides. Add this mixture to the strawberry blend.
04 -
Attach a candy thermometer to the saucepan. Cook over medium to medium-high heat, stirring occasionally, until the temperature reaches 230°F (about 45 minutes). Stir more frequently as the temperature exceeds 220°F to prevent burning.
05 -
Once the mixture reaches 230°F, remove from heat and quickly stir in the dissolved citric acid. Pour the hot mixture into prepared molds or pans immediately.
06 -
Allow the candy to cool completely to room temperature for at least 2 hours or overnight.
07 -
In a bowl, mix granulated sugar and powdered citric acid until evenly distributed.

Remove the candies from molds (or cut pieces if using a pan). Roll each candy in the sour sugar mixture until coated.

Store candies uncovered at room temperature for up to 1 week, covered in the refrigerator for up to 2 weeks, or in the freezer for up to 3 months (separate layers with parchment).
