In a small bowl, combine cornstarch with 3 tablespoons of the almond milk and mix until smooth.
3 tablespoons (22 g) cornstarch, 2 cups (480 ml) almond milk
In a medium saucepan, add the remainder of the almond milk and the sugar and heat to just below simmering on medium heat.
5 tablespoons (63 g) organic granulated sugar
Add the cornstarch mixture to the hot almond milk, whisking constantly.
Reduce heat to medium low and continue heating, stirring constantly until thick. To test that the pudding is ready, draw a spatula through the pudding, and it should take about a second for the pudding to fill back in.
Remove from heat. Cover with plastic wrap, pressing the wrap to the surface to prevent a skin from forming. Set aside to cool.
Prepare the peaches - wash, dry, peel if preferred, stone and then cut into slices.
1 pound (450 g) peaches
Place sliced peaches and lemon juice if using in a blender and pulse until you have a smooth puree.
1-2 tablespoons lemon juice
Fill the molds with alternating layers of the peach mixture and the almond mixture, then use a butter knife in the wells to roughly swirl the mix together.
Tap the mold on the kitchen surface to remove any air bubbles.
Place the lid on the popsicle mold and then place a popsicle stick in the center of each well, leaving about 1 ½ or 4cm of stick exposed.
Freeze for 8 hours or until solid.
Unmold the popsicles by filling a pan with hot water and placing the tips of the popsicle mold in the hot water for 10 seconds to make them release easier.
