Much of the appeal of sugar snap peas comes from their juicy, sweet crunch, which means you’ll want to take care when blanching them. They turn from perfectly crisp-tender to soft in seconds. The key is to have a bowl of salted ice water next to the stove and a slotted spoon at the ready. The salt in the ice water seasons the peas, and the ice stops them from overcooking. In this savory salad, they’re tossed with a garlicky dressing for brightness, and a creamy feta-yogurt sauce for richness. Serve them with crusty bread as a summery appetizer, or as a side dish for grilled fish or meats.
