Step 1: First things first, grab your silicone molds or a silicone cake pan. Place them directly onto a cookie sheet. This makes handling a full, wobbly mold so much easier!
Step 2: Take your fresh (or thawed frozen) raspberries and pop them into a blender or food processor. Blend them until they’re a smooth puree. Strain the puree through a fine-mesh sieve to remove all seeds, leaving you with 1 ½ cups of seedless raspberry goodness.
Step 3: In a medium saucepan, pour in your raspberry puree. Add the 1 ¾ cup granulated sugar and the corn syrup. Stir everything together over medium heat until the sugar dissolves and the mixture comes to a full, rolling boil. Keep stirring to make sure nothing sticks to the bottom!
Step 4: In a separate, smaller saucepan, combine the fruit pectin, baking soda, and the ¼ cup of filtered water. Whisk it well to combine, then bring this mixture to a gentle simmer. Once it's simmering, immediately add it to your boiling raspberry mixture. This quick addition helps the pectin activate properly.
Step 5: Insert a candy thermometer into the raspberry mixture. Continue cooking over medium heat, stirring frequently. You’re looking for the mixture to reach 230-240°F (110-116°C). This temperature range is essential for the gummies to set correctly.
Step 6: While your mixture is cooking, dissolve the powdered citric acid in the remaining ½ cup filtered water. Once your raspberry mixture hits the target temperature, remove it from the heat and stir in the dissolved citric acid. Work quickly here!
Step 7: Immediately and carefully pour the hot mixture into your prepared silicone molds. Fill them up, but try not to overfill.
Step 8: Allow your gummies to cool undisturbed for at least 2 hours. For the absolute best texture and firmness, let them sit overnight.
Step 9: Once fully cooled and set, gently unmold your beautiful raspberry gummies. For that classic candy store look and feel, roll each gummy in additional granulated sugar. This adds a lovely sparkle and prevents sticking.
Step 10: Your homemade Raspberry Pectin Gummies are ready to be savored!
