In a heavy-bottomed saucepan bring the butter, syrup, honey, and brown sugar to a boil, stirring until sugar is completely dissolved. Slowly pour in granola.
Increase the heat until the mixture doubles in height in the pan and becomes foamy. Insert a candy thermometer and allow to boil until the mixture reaches 240 degrees.
As the foam rises, sprinkle in the baking soda. Stir until the soda is completely dissolved.
When the foaming dies down, remove the saucepan from the heat and pour into a well-buttered jelly pan. After 15 minutes of cooling, score the candy to make it easier to break off. Allow the candy to completely cool and harden before serving with the dulse.
