These aren't technically a hot dog topping. They're flavored pickles. By the image above you can see some of their flavors. Some others on their website are Spicy Blu Raspberry Lemonade, Lemonade, Strawberry Lemonade, Strawberry Kiwi, Tropical Sunset, What-A-Berry, and more.

So far I've order some for Christmas gifts and myself. I've tried Pineapple and Peach Mango. Both were excellent. Salty, pickle-y, sweet and fruity, but not over done. I ate them out of the jar, but sliced on hamburgers would be good and I could see some of these chopped up as a relish on hot dogs, which is why I posted them here.

EDIT: I've since tried Watermelon and it's excellent. Atomic Fireball kind of had that hot cinnamon flavor and smell. I thought I was going to like that one the most, as I used to love the candy, but this one just doesn't hit for me. While accurate in flavor, it's just not for me. I've also tried Chamoy. It was a bit too sour tasting for me.
