My tastes in cottage cheese are more toward the mild and non-tangy. Safeway started carrying two types of Friendship cottage cheese - whipped and no salt added. These were pricey as I remember the price was over $3 and maybe close to $4. So after gagging a bit over the cost, I bought both.
I was disappointed in the whipped and didn't feel it was worth the price. It didn't seem very whipped, just a small curd cottage cheese and the taste was good but not so much better than Knudson that I'd pay the premium.
So I open the no salt added and it looks pretty much like the whipped with a small curd ... but the taste is wonderful. It made me think of unsalted butter, that sweet, clean, fresh taste. It is also a dense yogurt that didn't leak whey or whatever after being open for a few days. So worth the money.
It actually did what I hoped the whipped would do - it was a nice topping on a toasted bagel.
Long ago when I lived in Cambridge, Mass there was a place that sold cottage cheese from an Amish farm in Pennsylvania. It was so good that I still remember it and Freindhip no-salt had a taste that reminded me of that.
If you like tangy, Nancy's organic is the tangiest I've tried, there is actually a layer of what looks like sour cream on top that needs to be mixed into it.
On the local scene, I like Cowgirl Creamery which has a slight tang.
My default supermarket, everyday cottage cheese is Knudson. It just tastes better to me. I don't know why.
