01 - Preheat oven to 350°F. Spread almonds evenly on a baking sheet and roast for 10-12 minutes until golden brown and fragrant. Allow to cool completely before proceeding.
02 - Combine cooled roasted almonds, water, honey or maple syrup, vanilla extract, and sea salt in a blender. Process on high speed for 2-3 minutes until the mixture is completely smooth and milky.
03 - Pour the blended mixture through a fine mesh sieve or nut milk bag into a pitcher or jug. Press firmly to extract all liquid and separate the almond pulp.
04 - Stir in the heavy cream or coconut cream until fully incorporated into the almond milk base.
05 - Refrigerate the almond milk for at least 1 hour to allow flavors to meld and the drink to become thoroughly chilled.
06 - Pour over ice in chilled glasses. Optionally garnish with roasted almond slivers or a sprinkle of cinnamon.
