I'm generally a good cook. I don't necessarily need a recipe and if I see something on TV or in a restaurant I can imitate it pretty well. However, baking isn't my forte - unless it comes from a box or has very precise instructions.
For example, I once tried to make a meringue of sorts and was busily beating my egg whites to a frothy texture. The recipe said to use cream of tartar to "stabilize the egg" and give it a better, firmer texture (that's what she said). I didn't have any so I thought "cream of tartar, tartar sauce; po-tay-to po-tah-to".
The other day I saw a recipe for homemade macaroni and cheese. I was in the mood for something warm and comforting - like grilled cheese and tomato soup or mom's meatloaf or dad's chili. I went down to the store and bought all the required ingredients that I didn't already (think) I had at home.
The recipe for the sauce is basically melted butter, add flour and brown it, throw some evaporated milk, a ton of sharp cheddar, swiss etc., some mustard powder, salt and nutmeg. Sounds delicious, no? So here I am slaving away (not caring that the recipe apparently feeds an army).
The sauce tasted awesome, but there was something off about it that I just couldn't put my finger on. I threw the pasta in, mixed it all up and put it in the oven after topping it with some homemade bread crumbs (parmesan, crumbled bread and butter).
After it was done baking I helped myself to a bowl, trying to think of what the ingredient was that tasted a bit strange. Suddenly I realized that I had mixed up my container of flour for my container of...icing sugar.
