Spoon Type Thing With A Metal Plate And Hole?

My husband and I went thrift shopping and found this weird sterling silver spoon but we have no idea what it’s used for? Looked up the brand “reed and Barton” and found that it’s an old sterling silver company but couldn’t find a spoon like this anywhere. Anyone know what it is or what it’s used for?
