Raspberries are a mid-summer fruit that comes in several varieties—beyond the classic pinky-red, there are also black, purple, and golden colors. They're an aggressive breed: left unattended, they're likely to overtake a patch of land with their hollow fruit. Their tart, sweet flavor and appearance make them a popular choice for desserts, either whole or mashed, and they're great frozen for throwing into shakes.
Fun fact: each fruit is made up of about 100 smaller fruits called "drupulets", each with their own pulp and seed.
They're a good source of the antioxidant ellagic acid, manganese, vitamin C, and riboflavin. When purchasing, avoid berries that look mushy or moldy, and look for full, firm, brightly colored fruit. Since they're highly perishable, eat them as quickly as possible after purchase. Don't wash the berries until you're ready to use them, as this makes them more prone to spoiling.
