Our choice: Frozen
Why: It's worth noting that you're better off buying organic strawberries (here's scientific evidence that they taste better than conventionally grown ones). The problem is that fresh organic berries can cost $6 for a 16-ounce package. However, frozen are 25 percent less (we found a 10-ounce bag for just $2.79). They're great in smoothies and daiquiris, or you can defrost them to toss into oatmeal.
The only drawback: Limited use. You can't put them in strawberry shortcake or a fruit tart, since they'll be soggy when they defrost.
