Ask the (ex) professional pastry chef:
Use whichever butter tastes good to you. Salted butter has such a small amount of salt added to it that in most recipes, there will be little difference in taste. Unsalted butter may taste cleaner to you or not; it may also turn rancid faster. I used to have a problem with one brand of cultured butter going rancid and had to switch suppliers. Now all cultured butters taste too cheesy to me after that.
This is true. A food technologist told me that most processed foods have a little salt and sugar added not necessarily for preserving purposes, but because they go a long way in bringing out the flavor of the foods. I can’t count how many times I’ve been served bland cake frosting made of unsalted butter with no other salt added because the cook thought they were being enlightened or something.
Many American cookbook recipes up until the last 20 years were written for salted butter, and many still are. If you’re using your old red plaid Better Homes & Gardens cookbook, don’t worry about using unsalted butter. Even in that book, similar cake recipes have varying amounts of salt seemingly at random. As a matter of fact, I have not see any adjustments being made in recent cookbooks in the amount of added salt called for when using unsalted butter in baking recipes, just less salt overall. Cakes should taste fine with salted butter – a half-teaspoonful of salt more or less, spread throughout the entire cake, just isn’t that significant. True French buttercreams do need unsalted butter, maybe too a butter-heavy ganache (though both still will benefit with a some amount of salt added to round it out), but otherwise, I can’t even think of any recipes in the baking world off the top of my head that won’t be fine with salted butter. But again, if food tastes too salty to you, then definitely use what you like the best.
I agree! Land O’Lakes is great, always clean tasting. I prefer salted butter on my food, personally, but I can swing both ways. And half-salt definitely sounds like something I could get into.
My first time: When I was 11, I had dinner at the home of a German family. I was served pumpernickel bread with unsalted butter, both firsts for me (I’d only ever had Mazola and Wonder Bread, or for a gourmet treat, Pepperidge Farm Sandwich Bread). At first, I couldn’t stand the taste of the unsalted butter and brownish-black bread, but by the end of the meal, the heavens had opened and angels were singing! I didn’t have unsalted butter again for quite a few years, though.
