My "salad spinner" is a drawstring net lingerie bag. Wash your lettuce, basil, spinach, etc. and stick it in the bag. Go outside and twirl it around. This spinner doesn't take up any cabinet space!
Today I gathered lots of sandy basil. I put it in a pan of water and stemmed it, putting the leaves in a bowl. Then I fitted the lingerie bag over the bowl and dumped the basil into the bag. I washed it again in clear water and then spun it around. Perfect!
