Which method is listed for measuring plastic fats?

• A. Pack it in
• B. Displacement Method
• C. Use a dry measuring cup
• D. Level it off

Answer: (B)

Plastic fats are soft and compressible, so trying to pack or level them in a cup can give inconsistent results because air pockets and how tightly you press change the volume. The displacement method avoids that by measuring the actual space the fat occupies: you place the fat in a graduated container already filled with a known amount of water and see how much the liquid level rises. The increase in volume equals the fat’s volume, regardless of how the fat sits or its air content. This makes it the most reliable way to measure fats like shortening, lard, or butter. Packing or leveling would introduce errors, and using a dry measuring cup can also trap air or leave uneven fills.
