I came across this recipe from Serious Eats and had to try it. The baking soda had some sort of chemical reaction to the onions and quickly broke down the cellular structure. I wonder why.
Once I had the oniony paste, I then caramelized some sliced onions the old fashioned way. And I toasted some jalapeno cheese bread in the toaster with a slice of Monterrey pepper jack cheese on top. I also opened up a box of chicken broth. I then combined all of the previous into the finished product. Mmmm… It was pretty tasty!
