I decided to try making oat milk at home. The standard recipe that I found on several online sources looked really simple. The ingredients are: oat groats, water, and salt (optional). So I picked up some organic oat groats in bulk from a nearby Whole Foods.
The oat milk was so easy to make. Here’s the recipe I followed:
1/4 cup raw organic oat groats
4 cups water
1/4 teaspoon of sea salt.
Soak the oat groats in a bowl of water for about 8 hours. Rinse the oats and discard the soaking water.
Place the oats, salt, and 1 cup of water in a saucepan. Bring to a boil then cover and simmer over low heat for 40 minutes. Remove from heat and let the oats cool completely.
Blend the cooked oats with the 3 cups of water until very smooth (I used my immersion blender and added the water directly to the saucepan—which meant less dishes to wash afterwards!).
strain through a fine mesh strainer into an airtight container. I reserved the solids to use in a baking recipe (not sure what I’m going to make yet). The oat milk will keep for 3-4 days in the refrigerator.
You can also make raw oat milk.
Leave the soaked and rinsed oats in a colander in a cool spot for 12-24 hours to initiate the sprouting process. Then blend the oats with the 1/4 teaspoon of salt and 4 cups of water until very smooth. Let the blended oats sit for 1 hour before straining.
The texture of the oat milk is smooth and creamy. Cooked oat milk tastes nutty and I’ve read that raw oat milk has a grassier flavor. Homemade oat milk is a wonderful solution to a packaging problem. Store-bought oat milk (and other boxed liquids) come in a drink carton that is comprised of 75% paper, 20% plastic, and 5% aluminium foil. There is also usually a plastic pour spout on the top of the carton. Making your own is also far more economical. A quart of organic oat milk from the store will cost around 3 to 4 dollars. The oat groats I bought in bulk only cost $1.69 per pound.
f drinking the milk straight, you might try sweetening it with a little honey. Today I topped mine with freshly ground cinnamon. It was delicious.
