To help prevent molding and remove bacteria, dunk your berries in a vinegar bath of 1 1 cup (240ml) of water and 3 cups (710ml) of water. Then rinse them with water and dry them. Remove any berries that are moldy. Freeze berries that are very ripe to avoid letting them go bad and having to throw them away. Place the rinsed berries on a paper towel and use another paper towel to gently pat them dry. Soak up all the excess water on the berries with the paper towels. If you don't dry the berries completely, they'll grow ice crystals in the freezer which affects the flavor. Another drying option is to place the berries in a salad spinner. Spin them until they're completely dry. Lay a sheet of wax paper over a baking sheet. Then arrange the berries on the wax paper so that none of the berries are piled on top of each other. Try to separate the berries so that they aren't touching each other in the flat layer, too. If you don't have wax paper, aluminum foil will work. This is a process known as flash freezing. You're simply freezing the berries enough so that they won't stick together when you dump them into a container later on. Clear out a spot on a freezer shelf so the baking sheet sits completely flat. If it's tilted, the berries will shift and freeze together. It doesn't matter if you use a glass or plastic container, as long as it's completely airtight and freezer-safe. If air can get into the container, your berries will get freezer burnt faster and dry up. Using a freezer bag is another option. Press all extra air out of the bag before you seal it tightly. Write down the date you put the berries in the freezer if you want to remember when to eat them by. Or add 1 year to the date and write "Best by" with the future date. For example, if you packaged the berries on January 1, 2018, write "Best by January 1, 2019" on the container. After 1 year, the berries may still be safe to eat but they'll begin losing flavor. Avoid storing the container in the door of the freezer. This is the warmest spot and may cause them to thaw and refreeze if you open the door a lot. Frozen berries are great for smoothies. Simply remove them from the freezer when you want to make your smoothie and pop them in the blender.
What is a summary of what this article is about?
Rinse the berries in a colander in the sink. Dry the berries thoroughly with 2 paper towels. Spread the berries in a single layer on a wax paper-lined baking sheet. Place the baking sheet in the freezer for 5 to 10 minutes. Remove the sheet from the freezer and pour the berries into a container. Label the container with a permanent marker or sticker label. Place the container in the freezer for up to 1 year.
