Cut: holding your spatula so its broad face is to the left and the right (it looks like a skinny line from the top), cut down into the middle of your batter to the bottom of the bowl, using the spatula almost like a knife.
Scrape: turn your hand towards the bottom of the bowl and rotate the spatula so it's flat (under the batter), and laying on the bottom of the bowl essentially. Then scrape up the side of the bowl from the bottom to the top lip.
Flip: start to flip the spatula over so the broad face on the inside of the bowl becomes the bottom.
Fold: while flipping, move your spatula back over top the center of the bowl, so the flipping and re-center motions essentially "folds" that batter you pulled up the side of the bowl, over the top of the mixture.
Repeat: rotate your bowl a few inches so your next pass is shifted over from your first, and repeat this process as many times as needed (making sure you scrape the bottom of the bowl well on each pass), until everything is thoroughly combined.
