Line a strainer with a large round coffee filter.
Place 2 cups plain (not Greek-style) yogurt in filter.
Set the strainer over a bowl, deep enough to allow the liquid (whey) to drain.
Keep in fridge overnight.
You will wind up with yogurt having almost the consistency of cream cheese.
Have some in a bowl with honey drizzled on. They like it that way in Greece.
Why not use Greek-style yogurt in the recipe? Because drained yogurt IS Greek-style yogurt. Of course, you could just buy Greek-style yogurt. Just as long as you know there’s no secret formula, my work here is done. All you need is yogurt, a strainer lined with a filter, and reliable gravity. (Sorry, International Space Station astronauts!)
