I was making a lemon meringue pie, which called for 1/3 cup of corn starch and 1 1/3 cup of sugar, added to some quantity of water. Silly me, I put the water in the pot first, then the corn starch, and then — since I already had the 1/3 cup measuring cup out — I decided to measure the sugar as 4/3 cups. Problem is, I got distracted in the middle of measuring out the sugar, and I got to a point where I had no clue whether I had added 1 cup, or 1 1/3 cups, or possibly even 1 2/3 cups. Ooops.
Is there any way to recover from something like this? Preferably without throwing out everything and starting over?
(Obviously, the best way is to prevent yourself getting into such a situation in the first place: measure each ingredient into a separate vessel before you start combining, go ahead and dirty two measuring cups, don't get distracted, etc. But I'm sure we've all been there...)
For the record, for the pie in question I decided to quit while I'm ahead and proceeded with whatever mystery quantity of sugar was in the pot. I haven't actually tried the pie yet, it's still cooling, but it looked OK.
