Another vote for merangue cookies, plus a Dicey story:
I learned to make these as a kid and they became kind of a specialty, because they're easy, impressive and delicious. In those days, they were not typically sold in stores, only bakeries. One day I discovered tubs full of mini meringue star cookies at Trader Joe's. As I was checking out, I asked the cashier if she had tried them. She leaned toward me, lowered her voice, and said, "Don't open them in the car!" She was right, and .I have used that sage warning as a mantra ever since. I still make my own, including a white chocolate chip and peppermint version for the holidays. Yum!
Has anyone mentioned egg whites freeze well yet?
