Ways to use up lemon juice

I envy you... flavored lemonades of all kind... strawberry, mint, blueberry, the possibilities are endless!

Freeze the lemon juice in an ice cube tray, by tablespoon or more, and then once frozen take the cubes out and put them in separate wrappings. When you need it, pop it into whatever you are making.

Always good for marinades---and I love the sweetness of meyer lemons. Use it to baste roast or grilled chicken, or if you are ambitious make your own limoncello.

Never drink plain water again - slice thinly and add to a pitcher. Preserved lemons would be great too!

I'm joining the envy line. I had a friend in Berkeley who had one also, and she said she would actually gather them from the ground and throw them away because she couldn't use them fast enough. Suggestions: (1) zest them with a fine microplane and freeze the zest pressed flat in ziplock bags. (2) juice them, and freeze the juice. (3) count yourself lucky!

Lemon rice, cooked with beef stock.
Lemon deserts.
Make salad dressing/marinades.

Lemonade concentrate lasts forever in the fridge -- 1 cup lemon juice mixed with a heavy simple syrup (1 cup water/two cups sugar). Pour a couple of tablespoons of the syrup in the bottom of a glass, fill with sparkling water and ice -- bliss on a hot day. Not bad in champagne, either.

With a fat pinch of salt, use it to rub down your wooden cutting boards, butcher blocks, etc. Send USPS flat rate boxes full of them to your friends in other time zones. (Be sure to break the stem when picking, and not pull the stem out, as the fruit will begin to degrade immediately with the latter method.) Here's an article from the L.A. Times with 100 ideas: http://www.latimes.com... . My mother-in-law's mother had a wonderful recipe for lemon sherbet (early 20th century) that I've been meaning to get. Not sure how long it will take for me to get it. (I saw it during a family vacation, recently, but failed to copy it down!). It's a simple milk + sugar + lemon juice version. Have fun!! ;o)

Lemon curd, mrslarkin's lemon posset, dymnyno's lazy mary tart

These are all such great suggestions! That LA Times article had some really good ones. I love the idea of making Meyer lemon confit, and of sticking Meyer lemon peels into a jar of honey, perfuming the honey and candying the peel.

Also, I just remembered a favorite childhood pastime: licking sugar off halved lemons.

I also freeze aging lemons after juicing them and use for French 75s!

Lemon squares! Lemon pudding!

Great suggestions, everyone. I'm with SKK, I freeze it in cubes. Great for lots of reasons, especially cocktails! Speaking of, we made this a few weeks ago and it was perfect for summer: http://smittenkitchen.com...

Also, I've been making a lot of popsicles lately and lemon juice always comes in handy for those. Or you could make a granita or sorbet.
