Blue Castello is commercially produced blue cheese from Denmark made from cow's milk. This blue is a very creamy triple-cream cheese with a buttery flavor. Many people who don't care for sharp tasting blue may like the texture and the mild flavor. You can serve this cheese with simple table water crackers or a crusty baguette alongside fresh pear and apple slices. Serve a crisp Chenin Blanc or Sauvignon Blanc.
You can purchase Blue Castello at many well-stocked grocery stores and it is typically easy to find. You can find at Whole Foods Market as well as Trader Joe's. You can also purchase it online at Amazon.com: Blue Castello Cheese
