Ingredients
- blue spirulina powder:2 tsp
- warm water (to bloom spirulina):2 tbsp
- milk of choice (almond, oat, or dairy):2 cups
- full-fat canned coconut milk, chilled:1/2 cup
- honey or agave syrup:2 tbsp
- vanilla extract:1 tsp
- ice cubes:1 1/2 cups
- toasted shredded coconut (garnish):2 tbsp
- fine sea salt (pinch):1 tsp
Tips & Notes
- If you prefer a vegan version, use agave or maple syrup instead of honey and a plant milk you enjoy.
- Blooming spirulina in warm water helps it dissolve evenly and prevents clumps in the cold milk.
- Chill the canned coconut milk thoroughly (overnight if possible) so the cream separates and froths more easily for a thick foam.
- Adjust sweetness to taste — spirulina can taste grassy to some, so start with less sweetener and add more if needed.
