There's a cookie recipe I'm going to make that calls for 3/4 cup unsalted butter, melted and 1/2 teaspoon salt. We use I Can't Believe It's Not Butter as a substitute for butter, however that contains some Sodium already. So to figure out how much I should reduce the salt by I did the following:
ICBINB contains 55mg of Sodium per 2 tsp
That means for 3/4 cups = 36 tsp = 2*18 tsp, there is 0.055*18 mg or about 1 gram of Sodium in ICBINB
This next step I am not sure about. Using Google, it tells me 1/2 tsp of salt (or 2.5 grams of salt) contains 1000 mg of Sodium. Is this correct?
If the above is correct, that means 3/4 cup of ICBINB contains 1/2 teaspoon of salt, and since the recipe calls for 1/2 tsp salt with 3/4 cup of unsalted butter, does this mean I put no salt in the recipe since ICBIB already contains the necessary salt? Or should I put a tiny pinch of salt anyway just in case?
