This is a level that requires you to tackle the task in parts; firstly concentrating on racking up points, then on dropping the ingredient before you run out of moves.
Colour bomb + candy bomb combinations are essential - unless you can eliminate three or all the candy bombs by using a colour bomb on a candy whose colour matches at least three of the candy bomb's colour.
Mixing a colour bomb with striped candy before you have sufficient points will probably prevent you from scoring enough points, as the candy bombs will turn into striped candies or will be destroyed by an activated striped candy created from the combination, considerably reducing the number of possible points on the board.
You run out of moves either through detonation (at 35) or end of game (at 40) moves. It is best to try to complete this board within 35 moves, unless you get to within 5 or 6 moves until detonation, at which point you might spend a few moves working on a remaining detonator bomb before completing the task between moves 35 and 40.
