Screw Pine Shortbread: Lessons from an Experiment

As I think I've made clear, I like experimenting with flavors. I'm constantly scanning for products that sound interesting, particularly when traveling in new parts of the world. It was with this in mind that I was incapable of not purchasing a bottle reading "Kewra Essence: Screw Pine" at the sprawling Mustafa Centre in Singapore a few weeks ago. I had no idea what kewra or screw pine were, but they sounded intriguing. And $1 or so seemed a reasonable investment in curiosity.

I opened the bottle later; it smells a bit like rose water (which smells like, well, roses), but perhaps a bit earthier. Some Googling revealed that screw pine is another term for Pandanus, the leaves of which are often used to flavor southeast asian sweets (like kaya) and other dishes. Kewra essence, though, comes from the flower of this plant and has a quite different taste.

Ok…so what to do with my newfound bottle of rose-like liquid? I'm still not sure. It felt like it might go well with almonds in a dessert. Or maybe make an interesting cupcake or sorbet. I decided to experiment a bit by incorporating it into shortbread.

I find that rich, sweet desserts like shortbread or ice cream are good ways to see how a flavor will stand up, what it might work with, and how it is affected by sugar. I discovered this when making Thai basil ice cream a few years ago; revelation: sugar does magical things to basil. So I made some screw pine shortbread last night (lovers of word play will note that this name can also be interpreted as an imperative).

Outcome? Not very good shortbread, but some lessons. The kewra really is an "essence" and was not strengthened very much by the sugar at all. I had to add quite a bit (3 tablespoons!) to the dough to get any scent of it before baking, and the finished product only has the vaguest hint of the taste, mostly at the end. Making matters worse, an extra 3 TBSP of liquid means that the shortbread is sort of soggy, even with the top browned.

I think this is a flavor best combined with others, and it's not well-suited to being the focus of attention. I might try to use it as an enhancer for something nutty (as I suggested before), or maybe as part of a sorbet or syrup with berries or other sweet fruit. Stay tuned!
