Take the container, Mason Jar, or freezer bag of frozen cherry tomatoes out of the freezer.
Place the container/freezer bag/Mason Jar onto a plate or towel. Put it in the fridge. You can also take some flash-frozen tomatoes out of the freezer bag or container, put them into a bowl, cover it with plastic wrap, and pop the covered bowl into the fridge.
Leave the frozen cherry tomatoes to defrost overnight in the fridge.
Take the thawed cherry tomatoes out of the fridge. Use them as you like in your recipe, smoothie, or eat them directly. Bonus: freezing cherry tomatoes makes their skins slide right off after you thaw them—no need to blanch them beforehand!
