Cut the lime in half.

Place one half the lime in a food processor with the orange (quartered) and the granulated sugar.

Pulse until the orange pieces are pea-sized.

Add a 12 ounce bag of cranberries and process until it's still chunky but the mix is fairly uniform.

Reserve in a medium bowl with a lid.

In a small saucepan, combine the zest of the second half of the lime, the juice of the half lime, the brown sugar, dark rum, and 16 ounces of cranberries.

Bring to a boil and cook until the cranberries burst.

Lower heat to simmer and cover after stirring well. Cook for a couple of minutes until you have a jam consistency.

Remove from heat and let cool.

Mix together with the relish and serve.
