Add the tea leaves to a sealable container and pour in the vodka.

Shake the container and let sit for 20-50 minutes. You want a strong tea flavor, much stronger than you would normally would desire for regular tea.

Strain out the tea from the vodka. The vodka should have a green, tea color.

Add the milk to a large bowl and pour in the vodka. (It is important you pour the vodka into the milk and not the milk into the vodka!)

Stir the mixture gently and you will see the milk slightly separating.

Add the lemon juice bit by bit (~10 ml at the time) until the milk starts to break. When this happens you do not need to add more lemon juice.

Stir gently and let the curdles form. Stir every couple minutes.

Once the curdles have formed and the liquid on the top looks clear, let it sit for a couple hours undisturbed to let the curds settle.

Your vodka should be tea colored and smell faintly of tea.

Note: this recipe probably works with other teas as well. I haven't tried it but it should work in theory.
