Get it boiling and then add hops.
0.25 oz Centennial [9.50%AA] (55 min)
0.25 oz Centennial [9.50%] (35 min)
0.25 oz Cascade [7.80%] (20 min)
0.25 oz Cascade [7.80%] (5 min)
If your AA's are different, adjust accordingly to get the recipe's 21 IBUs. I believe the Cent hops were high so BM adjusted the boil time downward to get 21 IBU.
