You don’t see this every day. A family from Hawaii has grown the world’s largest avocado. Guinness World Records confirmed the 5.6 pound avocado is the heaviest on record. Mark, Juliane and Loihi Pokini live on the island of Maui, and said they picked the avocado from their tree in December. They say the certificate from Guinness arrived last week. The previous record-holing avocado weighed in at 5.5 pounds.
