Tip for Softening Butter and Margarine

Do you hate when you're cooking along, and you find that the recipe you're making calls for softened butter or margarine, and yours is in the fridge?  Well, here's what you do:

1. Put the cube in the microwave for about 5 seconds
2. Turn the cube over, so that the side that was on the bottom is now facing up and cook for 5 seconds
3. Turn the cube so that one of the sides is now on the bottom and cook for 5 seconds
4. Repeat step 2

All 4 big sides should have been on the bottom.  You may not need to do all 4 steps.  Just stop when the butter feels soft.
