Simulating the discontinued Lawry's Roasted Garlic Salt?
We know that:


1.1g contains 13% of the daily value of sodium which according to the FDA is &lt; 2400mg/day so 320 mg checks out correctly.
The total weight of the entire container is 201 g and the amount of servings is 183, so that checks out as well. (183 * 1.1)
The ingredients are in order of weight:


salt
sugar
modified corn starch
roasted garlic
spices (including oregano and basil)
natural flavor
extractives  [sic] of carrots


and that means the content of salt is highest, then sugar, then starch, ... until the carrot extract.
Salt is NaCl and 1 teaspoon weighs 10.7g so 1/4 teaspoon weighs 2.7g, not the 1.1g that the container displays, so the other ingredients must be lighter to come to a weight of 1.1g for the overall mixture
1 teaspoon of sugar weighs 3.95g  
1 teaspoon of corn starch weighs 2.77g  
1ml of garlic flakes weighs 0.35g, so 1 teaspoon weighs 0.07g
1ml of BBQ spices weighs 0.48g, so 1 teaspoon weighs 0.1g


"Natural flavor" and "carrot extract"  are really hard to find and are the ingredients with the least amount of weight in this recipe so I'll leave them out of this for the moment.

If we would mix 5 teaspoons of the above ingredients we'd come to a total of 0.8795g, which is too low so let's increase the cheapest and heaviest ingredient:


1.4 teaspoons of salt + 1 teaspoon sugar + 1 teaspoon of corn starch + 1 teaspoon of garlic +1 of spices is 1.09 g


That leaves you to play with 0.01g of natural flavor and carrot extract to get it just right, but the above should be 99% correct.
