FOR THE CARAMELIZED ONIONS:
Add the sugar, salt, and baking soda to the onions, mix to combine, and let it rest for about 15 minutes.
Add the onions to a large skillet, in high heat, and stir for 15 minutes. Deglaze the pan with sherry vinegar and a bit of water, then lower the heat to medium-low and let it cook for 15 to 20 minutes more Now, this is optional but I highly recommend you to add 1/5 cup of white wine 3 minutes before turning the heat off, gives a very elegant taste to the dip.
FOR THE GOOEY MELTABLE CHEESE:
Add all the ingredients into a high-speed blender cup, blend until smooth, then add to a pot, in medium heat and stir until it gets firm and stretchy, this will take about 5 to 7 minutes. Add to the pizza top along with your favorite ingredients, add the pizza to the oven and enjoy it!
FOR THE DIP:
Add the caramelized onions to the cheese, mix to combine, adjust the salt and acidity, add it to a serving bowl or an oven-safe pan if you decide to serve it hot, add some dried or fresh parsley or scallions to the top and enjoy it!
