How to Make Better Oat Milk
Soaking : Soak the oats by adding some water and leave it aside for 30 minutes.
Cold water : Don't blend the oats with warm water, as it releases the starch content from oats which will eventually turn into slimy consistency. So, it is best to use cold water for grinding.
Don't overblend : Blend the soaked oats for a few seconds. Over blending can turn the oats too slimy.
