Herein lies the problem with kaffirs, Fiona. I planted one a couple of years ago to my regret. For the number of times I used the leaves and/or zest, it was easier to buy same as needed.

You can make marmalade out of them either on their own (see link below for one recipe) or mixed with other citrus.

Could also preserve them (in saline) like preserved lemons. If you're interested, let me know and I'll hunt the recipe out.

Any, I'd be very interested, as I've just got a big bag of lemons yesterday. That would be great. :)

I take it you don't drink Midori? Because when I make the classic Midori Allusion (Midori; Cointreau; lemon-flavoured mineral water) instead of using plain ice, I use (when available) a whole ice-cub tray of frozen lime juice (can fit about 7 or 8 limes per tray). Fills a small jug, enough for 2 to 4 people (depending on how many have to drive). The lime juice really makes the flavours of the liqueurs come alive; wouldn't be half as good without it. And there's never any left over :-)

Herewith a link for preserved lemons, Spatz (easier to post alink than type it out again!!!). With kaffir limes, you'd need probably more juice than the fruits would produce; I'd use Tahitian lime juice. Otherwise, you can use acidulated water (1.5 tsp citric acid to 500ml water).
Also forgot to add to original reply - the zest is easy to dry and then powder as required, although by the time you got a tenth of the way down the jar, you'd probably have a whole new crop to use...

Thanks so much for the link, Andy. That's a great site. I'll give the preserved lemons a go. :)

dare I propose this butyou could give them away or sell them to your neighbours or go to market. we have a tahitian & a kaffir lime & always run out.We also have lemons mandarines and oranges in citrus.
Things to do with them. My husband and his cousins all put a slice of citrus preferably lime in their beer yep thats right, also in vodka etc etc etc. Then you can put it in your cooking or a cup of tea. Preserve them or make sorbet etc.
Cordial is sooo easy and fab. everyone asks me for the recipe.
Heat while stirring, 6 cups sugar and 1 litre of water, bring to boil, then simmer for 5 minutes, add 1-2 teaspoons of either citric acid or tartaric acid & remove from heat. Cool, and add 2 cups of strained juice of your choice.
thats it!!! Use as with bought cordial but I keep mine in the fridge & be warned it is much stronger than bought cordial.
Hope i helped

my favourite use for them is to juice them, strain the juice, and then use it as a hair rinse in the shower - beats any other bought product and completely natural. they are used this way in asia.

Hi there -

Being averse to housework of almost any kind, I sometimes let things slide a little...

Anyway, I discovered that there was some soapy scum on the shower glass and, putting brain into gear, decided to try a friend's tip; she uses half a lemon on her shower glass. Light-bulb moment! Yes, halved kaffir limes (this year we have squillions) work a treat - make sure you rinse the juice off and try to extract the pips beforehand - and now the glass is as it should be, looking shiny and new.

I freeze them, whole, and they thaw in time for the quick once-over.

I tried lime pickles and also marmalade with the kaffir limes before - both results were less than satisfactory.

Cheers - Margie
