How come "one" is used after "ramekin"? Is it necessary? Could you give me the usage example please?
The "one" here is a stand-in word for camera technique (or photography hack). Thus, you can understand "I'm going to use that ramekin one" as meaning "I'm going to use that ramekin trick/hack." "One" is often used instead of repeating the noun that was mentioned previously. Ex: A: You have so many skirts in your closet! B: Yup. I'm going to wear that pink one tomorrow. Ex: These are the latest sneaker styles. The blue ones are really popular.
