Brew the tea using hot water, then let it reach room temperature. This brings out the full flavor without melting the ice too quickly in the blender.
Grate the fresh ginger finely, releasing its spicy, aromatic oils. Measure out about a teaspoon of grated ginger for a bright, zesty kick.
Add the brewed tea into a blender, followed by the grated ginger and honey. Start blending on low speed to combine the ingredients smoothly.
Increase the blender speed to high and add the ice cubes gradually. Blend until the mixture is thick, smooth, and slushy, with a texture like a frozen beverage.
Stop the blender and check the consistency. It should be creamy, with small ice crystals, and well-frozen. If needed, add more ice and blend again for a few seconds.
Pour the icy tea slushie into glasses, and optionally garnish with a slice of ginger or a sprig of fresh mint for visual appeal.
Enjoy immediately with a straw or a spoon, experiencing the chilled, spicy-sweet flavor and icy texture in every sip.
