An adjustable measuring spoon is used by sliding the adjustment mechanism to the desired measurement marking.
Here's a breakdown:
- Adjusting the Size: Slide the adjuster to the measurement you need. The reference shows sliding the adjuster "all the way up till. One."
- Using with Liquids: The reference mentions that "this guy snaps off if you are putting liquids in it and need to clean it or anything." This suggests that some adjustable measuring spoons can be disassembled for easier cleaning, especially after measuring liquids.
In short, set it and measure!
