Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to infuse olive oil [title] Choose a bottle to use for your infused oil. [substeps] Find a bottle with a tight cover. Bottles with a cork stopper work best.

Ending1: Bottles with limited filling may not have the flexibility to infuse your oil into your liquid. You can use a french press, or a milk carton. Ending2: Bottles with lots of airholes tend to mean more residue. In addition, once all the essential oils are infused, the bottle will start to receive steam more effectively. Ending3: Metal lids can rust over time and can even affect the taste of the olive oil. Wash your bottles with soap and hot water and allow them to dry completely before use by placing them in the sun or leaving them out overnight. Ending4: The center part of the bottle is not covered by the tube. It works best if your label says that it holds a 6 by 6 in (15 by 15 cm) batch of infused oil.
