Anything that calls for doing several things at once because....
I don't have much counterspace these days and even less short term memory, it seems.
Washing the kitchen floor! I don't know why, but it always seems to be such a hassle, even though it's small now. Maybe it's because of those things that growl and snap at me.
Finally, although it's easy to do , I grudgingly make pesto. I love it, but have always felt a bit surly making it, ever since the first time I made it. I grew basil one summer, my first summer garden, actually, and had two HUGE bowls of basil leaves! I sailed into the kitchen, picturing myself as lady bountiful, handing out wonderful containers of pesto to all my friends. But....grrrrr, all I got from those huge bowls were two measly, small containers of pesto! Hahahha, I couldn't believe it! It tasted wonderful and I still make it whenever I can find enough to purchase without having to refinance the condo, but whenever I do, I remember that shattered dream of my youth!
