I made cream cheese accidentally when I let my yogurt drain too long in an effort to get Greek yogurt-like consistency. Most food surprises don't turn out this happily. If you're expecting the heavy, dense bricks you find in the supermarket, you'll be disappointed. This cream cheese is lighter and spreads nicely.
Add a bit of salt and any flavorings you want, like jam, for a morning bagel topper.
Drain yogurt in colander lined with cheesecloth overnight, in the fridge. Scrape yogurt into airtight container. This will last up to a month if the container has a strong seal.
