Cadbury's Turkish delight is not quite as good as real Turkish delight -- partly because it's presented in a chocolate coated bar, and the simple logistics of creating a bar means you need a stiffer product.
Real Turkish delight (actually called Lokum by Turks) does not contain any gelling agent, which the Cadbury's bars have to make them stiff. Lokum is essentially sugar, water, and a bit of corn starch boiled until it becomes a slightly soft confection that is somewhere between marshmallow and jelly. It is surprisingly not as sweet as one would think.
As for the rose water, consumed straight, yes, it does taste a bit like perfume, but it is an amazing ingredient in recipes -- or even in a nice cup of tea. Perhaps the easiest recipe using rose water, which also happens to be one of the most sublime desserts on the planet, is Moroccan orange salad with cinnamon and rosewater. It just works -- and people are always amazed at how good it is -- and stunned to learn the "secret" ingredient.
Here's my version:
4 navel oranges
2 Tbsp. rosewater
3 tsp. granulated sugar
1/2 tsp. ground cinnamon
Slice the oranges thinly and spread them on a platter. Sprinkle rosewater over the oranges. Next, sprinkle the sugar over them. Finally, sprinkle the cinnamon over the oranges. Let chill for about 30 minutes. Toss lightly before serving. (If you want to make a presentation of this, chill oranges with just the sugar and rosewater, and then sprinkle on the cinnamon just before serving. You could also garnish it with a mint sprig.)
Note: Get really nice oranges. The ones sold in the giant bags, where you get five pounds for $2, are usually not as juicy and flavorful as the ones that are sold individually.
So don't give up on rosewater just because you didn't like it straight.
