The roasted garlic salt involved, started by obviously roasting the garlic, however the difference was the next step where the pink Himalayan salt & the lightly roasted garlic are then baked together, so the full flavour is really infused into the salt.  This is then broken down by hand before placed in the little packets you see.

Try it on your steak, in your mash potato - virtually anywhere you use salt & want an added delish garlic flavour.
