Technical Writing

I was trying out a new cake recipe today.
It was given to me by someone who, perhaps, took notes from someone on their deathbed. It definitely didn't come from a book because it was very muddled and I doubt it had been tested. I ended up putting too much sugar, in the confusion. I read the recipe a number of times but it was not written in any order I could figure.
To make matters worse, there were numbered steps to make you think there was some kind of logic behind the whole thing. as though everything was carefully laid out.

There were several traps, all carefully crafted to make you waste perfectly good batter. I did not realize my mistake until the cake was in the oven and I was cleaning up.
When the cake is baked and still warm, you pour a mix of fruit juice, sugar and a bit of rhum. I had measured my ingredients but could not find the sugar... That is when I realized I had mistakenly added the sugar to the dry ingredients (mix all dry ingredients, it said). The trick was to notice the contradictions and make sense of them.

Ingredients
2 cups sugar (1 for cake, 1 for juice)
Whip butter, add sugar, eggs, zest

Later: beat together dry ingredients into batter. Later still: mix together sugar (what sugar!?), fruit juice and rhum (at that point, I was ready to drink the rhum and forget the whole thing - but I digress).

Oh, btw, for those who were wondering, the cake turned out fine.
After I was done, I rewrote the instructions following MY logic.

Who knew you were supposed to test the instructions... Maybe I should look for that job? Recipe tester sounds like just my line of work... : )
