Dice your 4 large peaches into roughly 1-inch pieces. You'll want them small enough to blend smoothly later. Don't fuss about getting them perfect — a rough chop works great. Toss them into a blender and blend until completely smooth, then strain through a fine-mesh sieve if you want an ultra-silky result (I do this step every time).

In a small saucepan, combine 1 cup water and 1/2 teaspoon agar-agar powder. Whisk constantly over medium heat until you see it simmer — this takes about 3 minutes. Keep whisking for 1-2 minutes after it starts bubbling to fully activate the agar-agar. The mixture should look slightly thickened.

Pour your peach puree into a large mixing bowl. Add 2 cups whole milk, 1 cup heavy cream, 3/4 cup sugar, and 1/4 cup honey. Stir everything together until the sugar dissolves completely (takes about 2 minutes of steady stirring). Don't skip this — lumpy sugar ruins the texture.

Add 1 tablespoon lemon juice, 1 teaspoon vanilla bean paste, 1/4 teaspoon ground cardamom, and 1/4 teaspoon salt. Stir until combined, then pour in your cooled agar-agar mixture and stir again for about 1 minute. Add 1 tablespoon corn syrup (it prevents ice crystals — trust me on this). Taste it now and adjust — if you want more peach flavor, you can add a tiny splash more lemon juice.

Let your mixture cool to room temperature for about 15 minutes, stirring occasionally. Don't skip the cooling step because you don't want warm liquid in your popsicle molds. I learned this the hard way when my first batch came out weirdly grainy (painful memory, but useful lesson).

Pour the mixture into your popsicle molds, leaving about 1/2 inch of space at the top. Insert your sticks and freeze for at least 6 hours, but overnight is actually better. The longer they sit, the creamier they get — I've never regretted waiting the extra hours.

To remove them, run warm water over the outside of each mold for about 10 seconds. Gently wiggle and pull, and they'll slide right out. If one gets stubborn, run it under warm water again — patience wins here. Store them in an airtight container so they don't pick up freezer flavors.
