How to Make It
Place nuts in a large glass bowl; cover with 3 cups distilled water. Let stand at room temperature 12 hours. Drain; rinse nuts, and drain.
Combine nuts and remaining 2 1/2 cups distilled water in a high-power blender; process 4 to 5 minutes or until smooth. Strain macadamia mixture through a fine sieve lined with cheesecloth. Save solids for another use. Refrigerate milk up to 4 days in a sealed bottle; stir or shake well before serving.
