I got a great idea, well it is Nigella Lawson's idea!
I put 5 or 6 frozen strawberries in a bowl and nuke them to soften them up a little. Then I add some powdered sugar, about 1-2 tablespoons, depending on the sweetness of the berries.
Then I take my immersion blender* (you can use a regular blender) and grind it up!
Voila, strawberry sauce.
*I always wanted an immersion blender but they were too expensive. Then last year some time I was looking on KitchenAid .com for a price on a pasta maker to attach to my mixer. I looked at the clearance section. There was one for $15. Baby, I snatched that right up! 2 weeks ago i got a cooks catalog in the mail and they listed the same blender for $150. Outrageous!
