Place the wax in the crock pot or double boiler over slowly boiling water until melted.

Separate the bottom of the egg cartons and discard the tops.

Fill each egg cavity with the wood chips. I started by only filling them 1/4th of the way through but later found that you can fill them completely.

Add the wax until the cavity is full.

Let cool overnight before cutting into individual cubes.

To light, place under a chimney full of charcoal, open-side up (so that the melting wax doesn't drip down) and light with a match or lighter.
