Directions

• In the bowl of a food processor fitted with its blade, soak oats in water for 15 minutes.
• Then, blend for about 45 seconds, until it looks homogenous and opaque. (There will still be very small shards of oat floating in the liquid.) Pour through a fine mesh sieve into a container (ideally one that has a pour spout), using a spatula to push as much liquid through as you can. You should get about 4 1/2 cups of liquid, the consistency of cream—this is your unsweetened oat milk. If you would like to thin it, just stir in additional water to your desired consistency.
• From here, the possibilities are endless—you could make a sweetened variety by adding maple syrup, agave, honey, or any soluble sweetener you like (to taste), plus a pinch of salt. You could add some cinnamon. Or, you could divide the batch in two, and make vanilla and chocolate flavors to drink with an amusingly patterned straw, as follows:
• Into one half-batch, whisk 1 tablespoon plus 1 teaspoon of maple syrup, 1 teaspoon of vanilla extract, and 1 small pinch of salt. (This is the vanilla flavor.)
• In a separate container, make chocolate syrup: Whisk together 2 tablespoons of maple syrup, 1 tablespoon plus 2 teaspoons of cocoa powder, and a large pinch of salt, until the cocoa powder has dissolved. Add the remaining half-batch of oat milk to the chocolate syrup and whisk to combine. (This is the chocolate flavor.)
• Note: Oat milk should be stored covered in the refrigerator. It keeps up to a few days. The milk will separate as it sits; just stir from the bottom to recombine.
