I buy whatever is the cheapest, butter is butter for the most part. But I don’t like unsalted butter for anything but baking. On toast it has no flavor to me.
I generally buy the Target Good and Gather brand, the only thing I don’t like about it is that they now pack in the longer, narrower sticks, like on the East Coast, I prefer the shorter West Coast style sticks, or cubes as I was brought up to call them. They fit in the butter dish better when there is still a partial cube left in the butter dish and I want to put a fresh cube out to get soft.
And I always keep at least 3 lbs. of butter in the freezer, and I was glad for this when the COVID-19 shortages set in a few weeks ago. You can’t find margarine around here in anything but those tubs of whipped crap. Even though I don’t like margarine and it isn’t as good for you health wise as butter, I would have bought a pound or two of Imperial if I could have found it when there was no butter to be had. During a couple of poor years for my family in the mid 60’s we used Imperial and it tasted the most like butter of any of the other margarines available then.
BTW, during WWII when everything was rationed, you could buy more margarine than butter with your fat coupons. But the dairy industry had a law in place then that prohibited the sale of margarine that was colored yellow to resemble butter. It came in 1 lb. rectangular plastic bags, with a capsule of carotene coloring in the block of white margarine. You then had to massage the bag to break the capsule and continue to knead the bag until the margarine was a uniform yellow in color.
My Mom was the youngest girl and this was her chore, which she hated doing. Therefore, margarine always had a negative connotation for her. Those couple or years we used Imperial were a real come down for her. When things got better financially she went back to butter and never used margarine again.
