Combine strawberries, Greek yogurt, honey, water, and lemon juice in your blender. Blend until completely smooth—this takes about 60 seconds. I find that stopping to scrape down the sides once prevents any hidden chunks, which will turn grainy once frozen. The mixture should pour like thick juice, not pulpy soup.

Add vanilla bean paste, agar-agar powder, salt, and milk to the blended mixture. Blend again for 30 seconds until the agar-agar dissolves completely and distributes evenly. Here's my confession: I skip this step my first time making these 4th of july strawberry popsicles cozy treats, and the texture always suffers. Don't be me. That powder needs full integration or you'll get seizing in the molds.

Pour the mixture through a fine-mesh strainer into a bowl. This removes any remaining pulp and ensures smooth, restaurant-quality popsicles. Stir gently and let it settle for two minutes while you prep your molds. The reason this matters: tiny fruit particles create ice crystals, and ice crystals mean a grainy bite instead of the glide you're chasing.

Divide the mixture among popsicle molds, leaving a quarter-inch space at the top. Insert sticks and cover with the mold lids. If you don't have mold lids, plastic wrap stretched tight works just fine—I've been there. Freeze for at least 4 hours, though overnight is genuinely better because it lets the agar-agar fully set.

Run warm water along the outside of each mold for five seconds. Pull gently on the stick—the popsicles should release easily. If they resist, wait 30 more seconds and try again. Rushing this step means ripped sticks and frustration, so patience pays off here.

Serve immediately or wrap in parchment and store in the freezer. The heartwarming summer popsicles taste best within the first 10 days, though they'll last three weeks. I recommend eating them right away because that first frozen pull is exactly what you've been imagining.
