They do look like Cherry Bomb.

I agree, Stoney, that they look like cherry peppers that I have seen photos of. Wish they were, too. But they are exactly what I bought, regular jalapenos, when I was too impatient to find the bigger jalapenos. Well there is always next year--or I may give a look in nearby nurseries for a hot cherry plant.

Do you have a pic of the jalapeno peppers from the same plant?

You should be able to find cherry bomb plants..they are not to hard to find.
One of my local nurseries had live plants this year.

Do you have a picture of the new pods?

Is it possible that you have a Jalapeno and cherry growing next to each other ?
Another possibility: You have crossed plant.

Stuffed jalapenos twice a week? Oh, I feel Sooooo sorry for you :P

Early season pods are often deformed due to moisture and/or temperature fluctuations interrupting the plant's uptake of Calcium and Nitrogen.

Here is a photo I just took. Definitely jalapenos, I think. Yes, the little round ones never grew and had no seeds. So, in the future, I will wait and see before I think I have the wrong peppers.

Thanks for all the helpful comments. Maybe the next photos I send will be of stuffed jalapenos!
