Just after the Hebrew holiday of Sukkot Jewish people start planning what to do with the ritual fruit called an etrog. It is one of the four species used in the holiday. It is a wonderful smelling fruit that can be put to use in marvellous and creative ways.
Brew the rind into beer
A local craft beer in Tel Aviv called Dancing Camel brewery makes a Sukkot beer using etrog rinds. Why not make your own? Or start simpler with a tej mead beer from Ethiopia.
Make etrog perfume
Perfumers distill essences of fruits and plants into oils that they deliver in a perfume. We know of an Israeli that makes an etrog perfume but why not try it yourself? Start simpler and make Ethiopian beer Tej, flavored with a bit o’ etrog rind.
Freshen up your closet
Keep it in your clothes closet. As it slowly dries out it releases a wonderful smell and will make everything smell nice.
Make an etrog for havdalah
Some people take an afternoon and push cloves into the etrog, covering the entire etrog. They then use the finished product for havdala, a Jewish ceremony performed after the end of the Sabbath, Saturday after nightfall. If you opt to do this, make sure you do so in one sitting since the etrog will dry out very quickly and you will not be able to continue later.
Make etrog-flavored vodka
Well you are not going to make the vodka. You will buy a good quality vodka and drop what rinds you have, minus the pulpy white bits, and let it sit for a month to release the smell of the etrog and to turn it into a flavor.
Make etrog jam
There are elaborate dishes such as etrog meringue pie, etrog cake or etrog risotto that people have historically made when they knew there were no pesticides on the rind of the fruit. If you find organic, or have a bounty of summer fruit to preserve like strawberries it is worth to make long-shelf life preserves and marmalade. But you will only have one or two etrogs. So follow this recipe to make etrog jam you will eat within a week or two.
