According to J&D's website, Bacon Salt is a low sodium, zero calorie, zero fat, vegetarian and kosher seasoning that makes everything taste like bacon. It is low sodium, zero calorie, zero fat and kosher certified. It does not make everything taste like bacon. The flavour is roughly akin to that of Bac'n Bits, the soy substitute for bacon bits made out of real bacon.
That being said, the spice definitely tastes good. The problem with Bac'n Bits isn't the flavour of it. The texture is all wrong. It's the wrong kind of crunchy, and it erodes in your mouth. Bacon Salt, on the other hand, will dissolve into whatever you are cooking, adding the wonderful faux-bacon taste to your concoction without adding that odd texture that bac'n bits would add.
Adding it to Chili, Macaroni and Cheese, or any other cheesy, spicy, or starchy dish definitely adds a nice touch to a meal. It pairs well with Garlic, Chili powder, Cumin, and any other spice that works well in a chili. It is also good in a sauce made out of Mayo and hot sauce.
It's fun to play with, and can add something extra to the old, tried and true recipes. It's definitely not a kitchen essential, however. I use it only occasionally, but that is more to do with circumstance than anything else.
I would recommend purchasing it if you see it in the store and you have some cash laying around. I wouldn't recommend running out and buying it right now, this very instant. It isn't going to make your food magically better, and it won't make you the coolest kid in the apartment block. I have no regrets buying it, and would buy it again should the grocery store have it in stock.
Arbitrary Product Score: 4 stars (wouldn't write home about it, would buy again.)
