Recipe comes from an asian blog. Here are her notes.. "The recipe originally calls for Greek-style yogurt - but I don’t have that in the stores where I live. Instead I use regular yogurt and strain. If you are using Greek-style, skip the whole straining part. Instead of embedding coconut flakes in the frozen yogurt itself, I use toasted coconut flakes as a topping. It adds gorgeous color, texture and flavor that you wouldn’t get otherwise. A note on the amount of yogurt to use: The original recipe calls for 6 cups of whole milk yogurt strained to yield 3 cups. I’ve made this recipe 3 times now, the last time I started with (2) lg 32oz containers of yogurt (8 cups) that yielded about 4 cups strained. I didn’t change the amount of sugar. It still was delicious."
