I did some experimenting after reading the posts in this forum and came up with a close imitation of Cupid's chili dogs. Listen this. You will need:

1 pack of natural skin hot dogs
hot dog buns
1 can of chili with no beans (Hormel's tastes a little strong. Find one that is a bit blander. I used a generic.)
1 can of Hormel's canned tamales
some beer (I used Heineken)

Steam the hot dogs and buns.

Heat your can of chili in a pot.

As the hot dogs and chili cook, take your can of tamales, stick them in a blender and liquify them (make sure to include all of the juice and no paper). Add the tamale mix to the chili.

Now, what I noticed at Cupid's was a distinctive beer taste. So, I added beer to the Chili. This will give the chili a unique tanginess like no other. Pour in enough beer to taste. Not much is needed to give it that special spike!

Stir all of the ingredients. It might be possible that the chili is too thin. Vaporize some of the extra liquid by leaving it on the stove for a bit and then letting it cool when you are satisfied with the consistency. This should thicken things up a bit.

Slap a dog in a bun, add liberal amounts of mustard, and slather with the new chili/tamale/beer mix.

I was quite surpised at how close this comes to Cupid's. It even has that reddish oily liquid at the top of the chili.

Let me know what you think. Bon apetit!
