Pro Tips/Recipe Notes
- If you cut the onions too thinly, they’ll cook down faster, but will become mush.
- If you’re like me and onions make you cry your face off, putting them in the fridge for 40-60 minutes before cutting them will greatly reduce the tears.
- The baking soda can add a bitter aftertaste if you use too much. I don’t recommend exceeding 1/4 tsp.
