I was skeptical when I saw the teaser on the Today Show, I’ve been eating tacos for quite a while and figured that I already knew a thing or two. But after watching the segment, I figured it was worth sharing.
The gist is that if you line your hard taco shell with a single piece of lettuce, it will trap the ingredients so they won’t explode and end up on your plate.
Now, I am a bit of a purist, and will always opt for crispy shredded cabbage instead of a single soggy lettuce leaf, but it does appear the physics are correct and this would work. I promise to try it out myself, and here it is for your own viewing pleasure.
