I see nothing wrong with the grammar, but I am at a loss as to the meaning of the last sentence. I made pancakes yesterday, so I cannot win today? . I answer questions today, so I cannot get a "Best answer" tomorrow?

I didn't win because it's not a pancake contest. I was just curious to see what kind of pancakes you usually make. I wouldn't have won because I made pancakes the day before the contest. (I don't understand the meaning of your original sentence, so this is my best guess.)

One passage seems not right. "I was just curious to see what kind of pancakes do you usually make." => ... what kind of pancakes you usually make. When you ask a question, you reverse the SV order and use the auxiliary "do" if it's a regular verb, as in "What kind of pancakes do you usually make?". When you use the same notion as a sub-clause in another sentence, you keep the SV order as you would in any plain statement, as in "I know what kind of pancakes you usually make". Plus, I find the references to "my win" and "wouldn't have won" a little unclear and strange. Do people use such terms when talking about a dish they made?
