Choose uniformly red strawberries. In doing so, avoid mushy strawberries that show any signs of mold. You will find fresh berries in a supermarket or grocery store all year round, but strawberries are best during summer and spring. You should check the local growers market or look for locations to choose your strawberries for the ripest and sweetest fruit. Whenever possible, opt for organic strawberries to avoid the pesticides that are commonly utilized in conventional growing. Also, you can buy frozen organic strawberries for additional sweetness and improved nutrition.
