Combine sugar and water in a 4 cup glass measure (with a handle). Do not stir. Microwave on full power for 5 minutes. Take out using an oven mitt, (glass may be very hot) and stir to dissolve the sugar. Place back in microwave on high power.
After about 15 minutes, watch closely, the mixture can overcook quickly, but you may need to continue for another 5-15 minutes (depending on strength of your microwave oven), until it reaches a dark amber color.
Remove using oven mitt and add Beach Bash Seed and Fruit Mix. Be very careful, the mixture will bubble and it is extremely hot. Stir until bubbling stops. Quickly turn out on a sheet pan in one thin layer (it may not fill the entire pan). Pan will be very hot.
Let cool completely on a wire rack and break brittle into pieces.
Store uncovered for up to 4 days. Humidity can vary storage time.
