My worst was a funeral, not a holiday. The lady across the street (and a church member) had a brother that died. I was making buttermilk-coconut pies to take and an extra for me. I finished them about 11pm and decided it was too late to take them over. Boy was I glad. I decided to eat a slice of mine. I noticed the pie pan looked strange. when I took a bite, I thought I'd been poisoned. I had used baking soda instead of cornstarch in the pies. They sat side by side in my cabinet. It's been 25 or 30 years and I still won't sit them in the same cabinet.
