Make homemade Greek yogurt with just 3 ingredients that are thickened overnight and slowly strained for a deliciously rich and tangy result. By making it yourself, you control everything - the thickness, the tartness and the added sugar! The longer the yogurt cultures develop, the more tangy the yogurt will be. The longer the yogurt is strained, the thicker it will be. Serve with sliced fruit or warm stewed fruit.
