Layered sweet tea peach popsicles with bold, never-bitter black tea and creamy macerated peaches in every bite.
The baking soda is the whole trick here — it mellows the tannins so you can brew a bold, full-flavored tea without bitterness once frozen. Use fully ripe, fragrant peaches; underripe fruit turns starchy and flavorless in the freezer. Don’t overfill the molds, liquid expands as it freezes and will push the sticks out. Pops keep well in the freezer for up to 2 weeks if the molds are airtight; after that, ice crystals start to dull the texture.
