I adapted our recipe from Feeding the Whole Family by Cynthia Lair. Seriously, if you don't own this book yet, just buy it!!! It's worth the money.
We started with the standing blender, but our crappy blender didn't do too well with step one:
blend 1/2 cup almonds and a few tablespoons of water into a paste.
We had success with the hand-blender and then transfered the paste to the blender with:
1 tbsp of brown rice syrup and 2 cups of water
Blend until combined. You can strain it through cheesecloth (which I would do if I wanted to put it in coffee or something), but we're just using it for cereal, recipes, oatmeal, chia pudding, etc.
And, yes, we did the math- it's WAY cheaper to make than buy, and you're in charge of the additives.
I WOULD make it again.
