When I put honey in a spoon or measuring cup, the residue stays and it’s hard to get all of it out. How do I make it all come out? Is there a way to measure honey without leaving honey on a spoon? 
As, since this answer other suggestions have abounded, let me clarify. These methods assume you want no wastage & also no cross-contamination of your source jar of the sticky component. They also require almost nothing in the way of 'extra equipment'.  Depending on what the next steps to your recipe are, I can think of three alternatives. None are perfect and each would suit a different scenario.   Tip it and leave it a long time. Heat it slightly. Microwave or sit the container in hot water.     or my favourite,   Rinse it out with the next liquid ingredient you will use in the same recipe; or for a spoon, stir your existing ingredients with it.
