You can use your citrus lemon salt to season your food as you cook, as you normally do. This will layer in a bit of the citrus flavoring.
The best way is to use it as a finisher. It is such a beautiful way to add both a salty and citrusy pop to whatever you’re eating. Just shake bit over your fresh seafood or into a zesty salad. Add a pinch to a margarita, even rim the whole glass. It is great in a bloody mary, and over anything grilled.
