Ex: "....and the other tomato-based ingredient that makes this an appealing combination."

I have to say, though, that there's something odd about the Spanish.
I'm just providing a translation based on my interpretation of what they probably mean, which is not really clear here.

Anyway, I hope you'll find this useful.

Yes, that's what "polarizar" means, and it was my original thought, but I'm not really sure.

In that case, would something like this work?
"....that creates a controversial appeal" (sounds legal to me)
or "that creates a controversial, yet appealing combination"?

You'll probably know best. Let's see what our colleagues have to say about this. I hope they will comment.

I just had another idea. What do you think of this other version?:

"....and the other controversial tomato-based ingredient that makes this an appealing combination."

You'll definitely find many references online to foods that are polarizing, but I don't find it to be the most natural phrasing. As always with these kinds of creative marketing texts, here are some ideas and wording you can play around with.

*I feel certain that "polariza en atractivo" goes with "tomate," not "la combinación."

Another translation of polarizar that I think is very natural is "tends to divide opinion." However, I wouldn't use it here, as I think it works better for a practice or combination (pineapple on pizza, etc.) than a food itself. I think this is more about like/dislike (appeal) than opinions.
