When Wendy’s started using sea salt, they also entirely changed their fries. Unless you were scaping the salt off and tasting it on its own, that’s probably not the change you were noticing.
If you can’t taste the quinine in tonic water, that’s…odd. Tonic is definitely sweet, but the bitter taste of quinine should usually be pretty noticeable.
Yes, there is. The sea salt has grain sizes at least three or four times larger, which, as I mentioned, makes it better for measuring, pinching, and working with.
“Morton® All-Purpose Sea Salts measure like table salt and are “recipe-ready” for cooking and baking. Plus Morton® Natural Sea Salt has no additives and is 100% natural. Harvested from the sparkling waters of the Pacific, these sea salts are Made by Nature”. The ingredients and grain size are identical to regular table salt. Cost is double.
In that case, yes, the larger grains can make a difference. It’s not iodized. The taste would be identical to regular (non-iodized) sea salt. Cost is about 5 times what table salt costs.
Perhaps the main taste difference is in the refining. Unrefined salts have other minerals and substances in them that add to the flavor and texture, refined salts do not.
