Liquid Lemon Tart

Never have I struggled so much to name an instructable. Other possible names:
Hot gold, liquid energy, hot lemonade -- the most accurate name, hot egg lemonade kind of makes it seem gross, rather than the most delicious, invigorating hot drink you have ever tasted. Liquid lemon tart describes its taste best -- though it does leave out the fact that this is a hot drink, perfect for nipping a cold in the bud. In my opinion it even beats chicken soup for the title of "best comfort food while lying sick in bed."

Step 1: Ingredients

You will need:

The juice from 1 lemon
1 egg
3 tablespoons of powdered sugar (aka confectioner's sugar)
Nutmeg and cinnamon (stick or powder) for garnish

Step 2: Instructions

Mix together the lemon juice, sugar and egg in a mug.

Slowly pour boiling water over the mixture, while continuing to beat it with a fork. Pour enough water to fill your mug. If you like your drink steaming hot, zap in in the microwave for a few seconds.

Step 3: Garnish

Grate some fresh nutmeg on top and garnish with a cinnamon stick. 

You can also use pre-ground nutmeg and powdered cinnamon if you don't have the whole spices in your pantry.

This is a "vintage" recipe which I found in Henley's Twentieth Century Formulas, Recipes and Processes, published in 1914. I wrote all about this book in my Make Glue instructable.

    i really want to make this, but i dont really like you think it would taste ok using some other type of citrus, like an orange, or lime? thanks:)

    I just read it once and I think to myself, "Oh this could be a great prank!". But no. It would be a great dessert instead.

    What would substituting honey for the powdered sugar do to this? The reason I mention it is because honey and lemon does a lot to free up mucus (yeah gross, but this is for when you're sick right?). A friend's son had constant breathing problems when he was little because of mucus and the doctor gave him all kinds of decongestant that didn't fix anything. After a while the doc said "look just take some honey and lemon in a cup, pour in some hot water and give it to him." They did and it cleared him up enough to breath easily.

    Just a thought.

    That's an excellent suggestion, and just the pretext I needed to make myself another one of these. Here's my conclusion: the honey version is probably better in terms of dealing with all the excess mucus, but if you're healthy and just looking for something tasty and warm to drink I like the powdered sugar version better. I used 2 tablespoons of honey instead of 3 tbsp powdered sugar, then, when the taste wasn't exciting enough, I tried melting 1 tsp butter into the mix. An improvement, but still, to my taste, not as good as the original. Next time I'll try adding butter to the powdered sugar version.... or perhaps malibu as christzilla suggests....

    Interesting! The powdered sugar has that big an effect on the taste? I was thinking that since it dissolves in the hot water it wouldn't, a very interesting result. I'll have to try this recipe unchanged then.

    I used 2 eggs, since my hens lay smaller eggs. Wonderful recipe! By the way, this book is on Google Books.

    I may have to try this. Maybe it will compliment the hot tea and a dash of honey I have been using to control my cold.
