First I'll give a base class: peanut butter shortbread. Then we can mess with it.
Mix everything with a wooden spoon. The dough will be stiff, or even crumbly, depending on how melted the butter is and the phase of the moon. Don't worry about it.
Pack the dough into a greased pan. Bake for 15 or 20 minutes. Take it out as soon as the edges turn golden brown; you don't want the edges to turn dark, and since there isn't any water in the dough, it happens pretty quickly.
While still warm, cut into squares.
I should point out that this is not the delicate poofter melt-in-your-mouth shortbread you may have heard of. This is manly, dense, walnut-laden, scrape-your-teeth-clean-and-thicken-your-blood cookie material. Cut it into small squares, because if you eat too many large ones, you will pass out.
But the point is, you can do anything to it:
Substitute sesame tahini for the peanut butter. (Halvah shortbread. Say goodbye to your arteries.)
Throw in chocolate chips.
Melt 3/4 cup of chocolate chips and substitute that for the peanut butter.
Use tahini, and also add three ounces of almond paste, plus 1/2 teaspoon almond extract.
Figure out something with hazelnuts.
Make two different kinds of shortbread and layer them.
Have fun.
The Palm 3 and related PDAs come with a solid plastic flip-down cover. (I guess for the Palm 5 it's flip-across.)You can also get transparent covers, and covers with voice-recorder hardware, and all sorts of other great stuff. Me, I have a square of Magic Slate taped inside the cover. So I can write on it. With the stylus, you know. (Credit to Eeyore for this idea.)
But I realized what I need to have, or more importantly, sell:
You know those Chinese-style window blinds, which are a roll of bamboo rods tied together? So that they roll up into a bundle, or unroll down to cover the window?
I want a Palm cover which is a roll of plastic rods stuck together with tearaway plastic.
They're styluses. About twenty styluses. When you realize you've lost your stylus, you just tear one off the end of the cover.
The cover unrolls a little long, so you can get five or six off before it's too short to work as a cover. And then what? You yank it off and buy another cover, and you still have fifteen styluses on a tearaway roll.
