You must clear all the frosting to complete part of the order, but it is important to clear the first two ones from the top within your first moves to let liquorice swirls fall sooner.
If you cannot make any combinations, you can use Lollipops for that.
When you have swirls on the board, try not to make matches next to them. If you do so, other swirls will not fall in that moment and you, probably, will fail to complete the order given the short amount of moves.
As always, you need patience, timing and/or luck to win this level. It may take you multiple tries no matter how skilled you are, but you already know that after living through many other hard levels over the course of 2,298 levels.
