Place the boiling water in a small bowl with the chai tea bag and chai spice. Allow the chai concentrate to steep for 10 minutes.
1/4 cup (60 ml) boiling water, 1 chai tea bag, 1/4 teaspoon chai spice
Carefully squeeze the tea bag (be careful – it will be hot) to extract all of its flavors, and whisk the chai concentrate to ensure the spices are fully combined. Then stir in the matcha powder until combined.
1/2 teaspoon matcha
Warm the almond milk and maple syrup (either in the microwave or a small pot over medium heat on the stove) until it reaches 150 °F (65 °C). It's best to do this on the stovetop, using a thermometer. If you don't have one, heat it just until it begins to steam.
1/2 cup (120 ml) cashew milk, 1 1/2 tablespoons maple syrup
Froth the almond milk using your favorite method – a handheld frother, a wand, in the blender, etc. Or skip the frothing step, if desired.
Add the chai and matcha concentrate to your favorite mug and top with frothed almond milk. Garnish with a sprinkle of chai spice and enjoy immediately.
