The nursery promotes it as ‘lemon on steroid’ but an etrog is a citron. It has a fragrant rind and sweet pith that is perfect for making glacé/candied peel. I slice it straight into a fennel salad; delicious.
The etrog has an extraordinary number of seeds and if you want to use the fruit for a Jewish religious ceremony, you’d have to grow one from a seed and have it certified as such. A fruit from a grafted tree won’t do. Blemishes are a no-no but it’s a fruit that bugs just love to take a nibble at. Mine would fail the test but all the same it would scent a bottle of vodka happily.
E is for Etrog, a fruit, a vegetable and a ‘flavour enhancer’.
