Lemon Juice Substitution

Last night, as I was preparing dinner, I
discovered, well into the cooking process, that
I needed lemon juice and did not have a single
drop of lemon juice in the house. 

I didn't need much and I really, really did

not want to go to the store for one little lemon.

I referenced my food substitutions book and found
that white wine, in an equal amount, is an acceptable
 replacement for lemon juice.  Apparently, this is
common knowledge for some but I never knew
it until yesterday. 

So I tried a Pinot Grigio in my recipe and it worked great!

Cheers!
