Do all sunflower seeds have salt with the same specific taste? What makes you think it’s the flavor of the salt they use, and not the sunflower (e.g. the scent of the sunflower seeds, or the oil that transfers to the salt)?
On McFries they just use a very fine ground salt. Sunflower seeds are sometimes packaged with a seasoned salt- mostly fine salt with a touch of paprika in it - try some Mrs. Dash to test this out.
McFries are fried in, and sunflower seeds are often packaged in, a partially hydrogenated vegetable oil. Try adding a drop or two of melted Crisco to your salt, and see if that’s the flavor you are looking for.
I don’t recall all the names of the salts that I have tried but I tried sea salt, Himalayan salt, table salt, I think all kinds of popcorn salt (I now use one of those).
I have not tried flour salt. How is this called on Amazon?
The sunflower seeds that I got had salt in the package that I loved the flavor of. I did get them in Israel though. All brands there had good salt. It is not used for other products in Israel. I actually did not try those in the states I admit.
This is what I do to parched in the shell peanuts.
Soak them raw, dry and place on a cookie sheet and parch them in a hot oven.
Nothing smells better IMO.
There are many different chemicals which are salts, but culinary salt of any sort is sodium chloride. Culinary salts differ only in the shape and size of the grains, and occasionally in very small traces of impurities which are almost impossible to taste. And the impure ones are far too expensive to show up at McDonald’s or in snack packs of sunflower seeds.
For the McDonalds salt, you could try just going to a McDonalds with a small container and asking them to give you some. The cost has to be low enough for them.
Yeah, I would say that type of finely grained popcorn salt is probably what the OP is looking for. It’s still just salt. So far as I can tell, McDonald’s just uses whatever the local foodservice salt is (there doesn’t seem to be international standarization on this.) For example, in Canada, they use salt from St. Claire, Michigan. They do seem to have a granulation specification, but that’s about it that I see.
