This is really great, I make it all the time but I never used jalapenos before. In addition to removing the seeds and stem the membrane, which is actually the hottest part, should be removed. I think the last reviewer did not remove the seeds from the pepper. This does make a big difference. If you find the tomato juice is too thick to your liking just add a little water. Very simple. I always feel so energized when I have this drink.
