I just made my first (successful) batch and it’s ok, but it doesn’t really taste like store bought at all. And the goal is to get a similar end result since that can be used get other people into making their own instead of buying it since it’s marked up so much.
If you're talking about the stuff in the jar, it's missing the sharpest/most aromatic flavors of fresh garlic. That's just the price paid to make some foods shelf-stable, unfortunately.
The difference will be pretty noticeable, and since it's a blender recipe you don't even have to prep the stuff beyond peeling it.
