These are all some excellent additions to savory dishes.

An excellent addition to any sweet fare you have is real Vanilla Sugar. Not the packaged stuff you get at the supermarket. Just place a couple of split vanilla pods into an airtight jar of white sugar. It'll take a day or so for the flavour to permiate. Leave the pods in there, and use the sugar as need be.

Subsitute this in almost any sweet recipe, sprinkle it on top of cakes and muffins before baking, or just sprinkle it on top of any crud you're eating.

With a phial of vanilla sugar, and a phial of shoyu/wasabi mixture, the decades you're sentenced to in that Turkish prison will just glide by !
