How to Soften Cold Butter Quickly
If you need to use cold butter that’s been in the fridge, here are some quick methods to bring it to room temperature:

Microwave Method: Cut the butter into smaller pieces and place them on a microwave-safe plate. Heat on low power for short intervals until it softens, being careful not to melt it.
Grating Method: Use a box grater to shred the cold butter into small pieces. This increases the surface area, allowing it to soften faster at room temperature.
Signs That Butter Has Gone Bad
Even though butter is generally safe at room temperature, it’s important to recognize when it has spoiled:

Off Smell: If the butter has a strange or sour smell, it’s best to discard it. Fresh butter should have a light, rich aroma.
Off Taste: If the butter tastes sour or unusual, it’s time to throw it away.
Mold or Discoloration: Visible mold or any significant color changes indicate that the butter is no longer safe to eat.
