Duck fat: This is sold in jars at specialty stores, butchers, or online. While I love the flavor it adds, you can substitute olive oil. When using duck fat, make sure it's melted (it's solid at room temp) but not hot.
Dressing quantity: Depending on how much lettuce you use, you may have leftover dressing. You can store any leftovers in your fridge for up to 5 days. https://www.theendlessmeal.com/pourhouse-caesar-with-hickory-sticks/
