Squash: Butternut

Peak Season: September to November

Perfect Pick: Should feel dense for its size with a rind that is smooth, hard, uniformly tan, and free of splits. Being able to easily push a fingernail into the rind or scrape bits off indicates an immature, less flavorful squash.

Handle with Care: Butternut should be stored outside the fridge in a cool, well-ventilated, dark place, where it will stay edible for up to 3 months.

The Payoff: Huge amount of vitamin A to ramp up your immune system.
