Wash the fresh strawberries and remove the green tops—I do this under running water and use my thumbnail to pop out the center core. Place all 2 cups into a blender with 1 cup water and blend until completely smooth, about 45 seconds. You want zero visible seeds because they'll make the texture gritty when frozen, and no one wants to bite down on a hard seed while eating a popsicle.
Pour the strawberry puree through a fine-mesh strainer into a large bowl, pressing gently with the back of a spoon to extract all the juice. This step separates the pulp from the liquid, which is why your strawberry lemonade popsicles cozy recipe will have that professional texture. I honestly skip this some summers and regret it within two bites—the difference is dramatic.
Add 3/4 cup granulated sugar, 1/4 cup fresh lemon juice, 2 tbsp lemonade concentrate, 1 tbsp honey, 1/2 tsp citric acid, and 1/8 tsp sea salt to the strained mixture. Stir for exactly two minutes until the sugar fully dissolves—this prevents crystallization once frozen. You'll see the mixture turn slightly thicker as the sugar breaks down, which signals you're done.
Heat 1/2 cup coconut milk in a small saucepan over low heat for about three minutes—don't let it boil. Remove from heat and whisk in 1 tsp agar-agar powder, stirring constantly for one full minute. The agar activates in warm liquid, and this is the single most important step because it's what gives you that firm hold instead of an icy slush.
Pour the agar-coconut mixture into the strawberry mixture and stir until completely combined, about one minute. Add 1 tsp orange zest and 1 pinch ground cinnamon, then stir one final time. The zest and cinnamon add warmth that most people can't identify but absolutely notice—they make the whole thing feel intentional, not accidental.
Let the mixture cool to room temperature, about 15 minutes, then carefully pour into popsicle molds, filling each one 3/4 full. Insert the wooden sticks and freeze for six hours minimum, though overnight is ideal. I always freeze mine before bed and they're perfect by mid-morning.
