Like many of the other reviewers, I was looking for a recipe very close to the Campbell's Soup version. This recipe is OK (with one change), but it isn't close enough I'd consider it a substitute. The texture is right, the taste is wrong as far as matching Campbell's. I've tried this recipe twice (with variations) trying to get it closer to the actual soup recipe and I would suggest the following:
1. First time I read this recipe, I was extremely dubious about adding the white wine vinegar at the end, it seemed like too much acid, especially with the tomato paste as well. I was right, it was too much, I couldn't even eat it. Recommend that you omit the vinegar entirely, or if you really like vinegar, add in small amounts and taste in between so you don't go too far.
2. The other reviewer who said there's too much tomato paste was right. Did 4 ounces the first time and it overpowered the other flavors. I tried putting only 3 ounces the second time, and even then, the resultant color was too red, the tomato taste was still too strong. The predominant flavor should be smoky, and the beans, not tomato. I'm considering leaving it out altogether in a future attempt.
3. Way, way too much thyme. I would consider halving it in future, or leaving it out altogether if you're trying to replicate Campbell's. There's no hint of thyme I can discern in Campbell's (I tasted it right out of the can compared to this recipe).
4. Find some way to introduce more smoke flavor into the recipe. I'm not sure how best to do this, adding more liquid smoke didn't do it. I added some ham base (that is used for stock) and that had more of a smoky flavor, and increased the ham flavor, but perhaps I didn't add enough. I might also try adding some smoked ham in future.
This is an OK recipe as long as you omit the vinegar at the end, but if you are looking to replicate Campbell's Soup, it isn't close enough as is. Adjustments are needed.
