Most kinds of jelly come in a jar. In order to open it, grab the lid and twist.
For other kinds that may come in a bottle, you just flip open the lid and squeeze out your jelly.
At this point you need to place the jelly on the bread.
If it's in a jar, you may need to use the butter knife to get it out.
Just leave it in a little heap in the center of the bread for now, making sure you have a good jelly to bread ratio.
