Pesto Potato Salad

To test boiled potatoes for doneness, use a skewer or the tines of a fork rather than the tip of a knife so you know they’re truly tender (a knife slides through the flesh way too easily). To test boiled eggs for doneness—wait, you can’t! Just make sure the eggs are room temperature when you drop them in the water (otherwise they’re prone to cracking), set a timer right away, and have an ice bath at the ready.
