I think this product has been in existence since time began, or so it seems. But, when you get it right and even improve the product like Kraft has done here with the addition of Romano cheese, well, if you don't buy it, you're missing out. I use this cheese in particular with a garlic/cheese roll recipe that is outstanding, but it's also superb on everyday pasta recipes. The clumping is minimal, it's ALWAYS real cheese (not so in the store-brand varieties), and it's made by Kraft. Great stuff, been using this one for years, highly recommend!
