Using a mortar and pestle, grind the lavender into small dust-like pieces.
Add the crushed lavender and almond milk to a small saucepan over medium heat. Let it come to a simmer, but don't boil it.
Meanwhile, add the matcha and hot water to a small bowl. Use a bamboo whisk to quickly whisk back and forth in an M or W motion until foamy.
Take the milk off the heat and pour in the matcha along with the vanilla extract and agave nectar (or honey).
Use a handheld milk frother to whisk the latte until foamy. Pour into a mug and enjoy!
Notes
Almond Milk: We recommend using a barista blend since they're better at frothing and don't have a "burnt" taste when heated. The texture is also thicker and richer than regular almond milk.
For a smoother drink, sift the matcha before adding the hot water.
