What is the water displacement method for measuring solid fats like butter or shortening, and when might you use it instead of a traditional dry measuring cup or scale?

Question

Discover the water displacement method for measuring solid fats. Learn what this clever technique is and when it's the best option to use.

Answer 1

The water displacement method measures solid fats by submerging them in water and measuring the volume of water displaced. This method is useful for irregular amounts or when you lack dry measuring cups or a scale.

Detailed Explanation:

The water displacement method is a clever technique for accurately measuring solid fats, especially when you need a specific amount that isn't easily achieved with standard measuring tools. Here's how it works:

1. Choose a liquid measuring cup: Select a clear liquid measuring cup with clearly marked measurements.
2. Fill with water: Pour water into the measuring cup, but *subtract* the amount of fat you need from your target water level. For example, if you need 1/2 cup of shortening, fill the measuring cup with water to the 1/2 cup *below* the 1 cup mark (so, to the 1/2 cup mark).
3. Add the fat: Carefully add the solid fat to the water. Make sure the fat is fully submerged. You may need to cut the fat into smaller pieces to help it sink.
4. Measure the final water level: Observe the new water level in the measuring cup. The water level should now be at your target measurement (in our example, the 1 cup mark).
5. Remove the water: Carefully pour out the water, leaving the measured fat in the cup. You can then scoop out the fat for use in your recipe.

This method works because 1 milliliter (mL) of water is approximately equal to 1 cubic centimeter (cc) of volume, allowing you to accurately measure the volume of the fat.

Pro Tip:

For easier cleanup, lightly grease the measuring cup with cooking spray before adding the water. This will help the fat slide out more easily after you've measured it.
