Actually I am eating a full fat Greek yogurt right now. 10%. Wow it's rich, and won't do any favors for the midsection.
In the US I used to like Dannon.
Anyway, I've made yogurt a few times. The last time I got creative and added Nescafe espresso powder and also powdered milk and I thought it turned out artificial and gummy. I think it was 1/4 cup for 48oz of yogurt (in 6 individual cups).
A Greek yogurt I like here is 0.9% fat and has both lemon flavor and chunks of softened lemon in it. It's awesome. I'll have to keep experimenting with homemade.
