Bring one cup of water to a gentle simmer in a small pot. Remove it from the heat and steep the Earl Grey tea bag (or loose leaf) for about five minutes. If using lavender, add it at this step for a light floral note.
Once the tea has steeped, stir in the almond milk and gently warm the mixture over low heat. Avoid boiling.
Add the vanilla extract and your chosen sweetener, adjusting the sweetness to your preference.
Strain the mixture through a sieve to remove any lavender pieces or tea leaves, ensuring a smooth drink.
Froth extra almond milk or cream using a frother if desired, and spoon it on top of the latte for a luxurious finish.
Garnish with a light sprinkle of lavender or cinnamon for added flavor and aroma.
Serve immediately and enjoy your homemade Low Carb London Fog Latte.
