This bar of Galaxy is designed to be swirled in a hot drink. When I saw that it was Shortbread Crunch I assumed that the main part of the chocolate was biscuit, and that this was ultimately for dunking.
What I actually had was a fairly regular bar of Galaxy, with a few shortbread bits mixed in, all in a new layout. The design inside shows that that each piece is meant to broken off and swirled in coffee or hot chocolate, hence the name Swirlers. I went to break one Swirler off, and two came away, I tried to break these in half and they split, but into several parts. I tried to break one off the other side, and it came away neatly. Not the best start though. I made myself a nice big mug of coffee.
Next I swirled it in my drink, but it made the chocolate melt and slippery. I ended up with a finger imprint on the end I was holding and sticky fingers. There wasn’t enough biscuit to soften like a proper biscuit, which is the best part of dunking. The drink gained nothing from the traces of added chocolate, and the chocolate gained nothing from the hot liquid.
Conclusion, I just ate the rest of the bar like regular chocolate, and it was divine. I’d forgotten how good Galaxy can be.
