Notes

  • Adjust — Adjusting is the key when it comes to sauces and Subway’s sweet onion sauce recipe is not an exception. You will be using lots of ingredients with various flavor profiles, so feel free to adjust according to your taste. Decrease the sweetness or increase the heat, it’s all up to you.
 
  • The jar — Although this should probably go without saying, make sure to wash, rinse, and clean the jar you will be using before getting to work. Make sure to test the lid while you’re at it.
