Typically horchata is a sweet drink made with white rice, cinnamon and sugar. Sometimes almonds are added to the rice drink to give it a little different taste. I make mine purely out of almonds, a cinnamon stick, and coconut sugar (I am sure honey would work just as well).
1 c almonds
4 1/4 c Filtered water
1 cinnamon stick
1/2 c coconut sugar
Place almonds and cinnamon stick in a glass jar, or dish. Add just enough water to completely cover the almonds with about 1/2 inch of water above them. Soak at least 8 hours or over night. After soaking, drain the almonds and cinnamon stick and place in a blender with the 4 1/4 c filtered water and coconut sugar. Blend for about 1-2 minutes. The time will depend on your blender. Strain the mixture using a milk bag, cheese cloth or thin dish towel. Store in a glass jar for 4-5 days. I love to drink this over ice. For an extra adult treat add a splash of Ammaretto or Kahlua. That will make it not Paleo, but a nice treat to enjoy occasionally.
