Yep, you can freeze avocado too. Blended into a homemade ice cream or gelato recipe, avocado can help provide a soft texture often missing from homemade frozen goodies. Unless eaten right away, homemade ice cream can sometimes freeze solid because it lacks the chemical emulsifiers of commercial products.
Avocado imparts a lovely green color and a mild flavor. You can enjoy it plain or add the additional flavorings of your choice.
