Momos taste better than love letters, though if you dip them in chocolate sauce, they are pretty rad too. Or you could make a love letter pie, but that needs the works so I don't usually eat that.
I am not sure if the color of love letters affects their taste, but I personally prefer purple love letters, dipped in chocolate sauce and caramel, with Kaju-kissmiss topings. I think they call it burberry pie. Or blueberry pie-- though I suspect your letter has to be written in blueberry to have the name 'blueberry' attached to it. Yellow letters are good to, though most of the time they look too much like excreta than I would want them to look(though, of course, I don't want them to look like a hobo to begin with, so it doesn't matter anyway).
I am led to believe that people of the Old Ages made love letters in blood. In their own blood. Those cannibals. There's a specific word that means self-cannibalization, but I forget it now, and instead am reminded of a friend who scratched the name of the girl he had a crush on on his arms with blade when he was in grade six. The point I am trying to make is, I think, that love makes you wanna eat yourself. Or love letters. Since I am the type who likes eating, I decided to make a recipe out of it.
Love letters never taste good with tears. They are too salty for a sweet dish, wash all the tasty blue-purple ink away, and EWW dude, what kind of sicko bakes food items with tears inside them? But boogers are fine, though. Totally awesome. If you want to get sued, that is. So, first rule with making and eating Love letters: ABSOLUTELY no bodily fluids or any other part remotely attached to the human body, and that includes nails, hair, earwax, eyeballs and sweat. Also, NO kidney stones. Kidney stones are too buttery.
Now you need the content. Make some stuff up, but don't be a judgmental bitch(wherein men can be bitches too). For reference, Shakespeare was one of the most judgmental dude everrr, but even HE could not beat the bitchy judgmental writers of classical hindu texts. They make you feel anyone without the eyes of a deer, the skin of a nymph, the hair of... Rapunzel(?), the manliness of Hanuman(who, incidentally, is also the hairiest dude in history...but then, body hair in men was the IT thing, so we can't even do that anymore), the whiteness(soo racist) of snow, the voice of nature, is unworthy of your love, and you should totally not write a love later to him/her, which you will later eat. The letter, I mean, not the person. I mean, if the person does not have any of those qualities, what will you write anyway? What do people write anyway? I, for one, was fortunate enough to read a love letter one of my friends received in grade 8(which later turned out to be fake, which he realized only after he called the girl, told her he hated her, she was bewildered, told him she never wrote him any kind of letter, and he would not have to worry about getting such letters because he was the last guy she would send such letters to, but its all besides the point), so I know what a modern-day love letter looks like.
The second thing one should remember while writing love letters is that Love letters should be addressed to Human beings and other anthropomorphic creatures, and certainly not other beings, like animals, for example. Writing a love letter to your dog or your parrot may sound cute at first, but once the novelty wears out, you are going to be known as the person who had a thing for her pet for the rest of your life, so you take care of that.
Third thing: try to make the addressed as real as you can. Corollary: Try avoiding imaginary lovers in your love letters. I mean, I may not understand why so many girls have a thing for the hairy-ickyicky manliness of Jacob(who, I've been told is a WOLF, breaking the second rule already) from Twilight, though I suspect hairiness for men may be coming back to fashion, but I still think it is best to avoid those things. No, Harry Potter is just as imaginary as Jacob, and you cannot have him as your lover either. Any character from Salman Rushdie's books is totally okay though.
After you are done writing the letter, slowly dip it in a cup of liquid chocolate. After every inch of the letter is covered with chocolaty yummyness, put it in the freezer for a few hours, add caramel, the topics, put it in the freeze for several more hours and then eat. Yum!
