For the swiss chard:
- Cut the Swiss chard stems crosswise into 1⁄4-inch-thick slices. Place in a jar or other airtight container.

- Slice the Swiss chard leaves and refrigerate them separately as well.
For the Raisin pure:

- Put the raisins in a blender and pour the boiling water over them.
- Purée until very smooth. Add the lemon juice and purée again.
- pass through a chinoise.

For the pork belly:
- The day before: Mix the salt, sugar, and paprika in a small bowl to make a cure.
- Sprinkle half in the bottom of a container that will fit the pork belly snugly.
- Place the meat on top, then cover with the remaining cure mixture. Cover and refrigerate overnight for 12 hours.
- Rinse the cure off the pork and pat the pork dry. Cut the ½ pork belly in long strips about 2.5 inches wide.
Before service: (cook only whatever you think you will be selling for that service)
