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.
I ordered Watermelon as a gift, so I'll have to order one of those for myself. I already have Atomic Fireball, Chamoy Twist with Tahin, and Habanero Mango on order, but I'm down to try every flavor.
