If I use salted butter (calls for unsalted), should I omit the 1tsp. salt that the recipe calls for?
You could cut back, if you had a mind to. I generally put all the salt in regardeless of what kind of butter I'm using. This either makes me a bad baker or it just doesn't matter that much - anyhow, this recipe turns out great no matter which way I do it! It's by far my favorite cookie recipe!
I always leave out the salt if I'm using salted butter. If not, the cookie tastes a little bit salty. I guess it is a matter of personal taste.
Okay, so one "yes" and one "no". Who wants to be the tie breaker?
How about I split it down the middle, and say you should use half the normal amount of salt? (That's what I have done when dh bought the wrong butter.)
I also leave it in.
With all the icing that eventually covers it, they won't be salty.
If you want another opinion...I would leave it out.
I'm sure it would be OK either way,. but....I always use unsalted butter and the last time I made the NF recipe, I accidentally put in 2x the salt it called for. The cookies tasted salty to me - even with the icing.
