Riddonkulous

I am a creamy dairy product born from fresh white milk but transformed by tiny helpful bacteria through the magic of fermentation. I live inside a small plastic cup or squeeze tube in the coldest aisle of your local grocery store. People love to scoop me up with a metal spoon for breakfast or a healthy afternoon snack. I have a naturally sharp and tangy taste but I am frequently blended with sweet strawberries vanilla beans or wild blueberries. You can top my velvety layers with crunchy honey granola or fresh fruit for extra texture. I am absolutely packed with active probiotic cultures that keep your tummy happy and digesting smoothly every single day. Can you guess my exact identity now?
