Hi! I love making cakes and since I discovered ROOUXBE I've been taking notes of all your cakes. My problem is that I'm an expatriate American living in Milan, Italy where it's impossible to buy a measuring cup! Is there any way to convert the flour, sugar, butter, etc. into grams? Otherwise I'll have to wait for some friend or relative to bring it to me from the States. Bye Angela

I just Googled cups to gram conversion and I found this calculator so I hope that helps! Otherwise you could always guess I suppose! :)

Here's a good link as well:

There are entire classes and books written on culinary math, and if you ever go to a formal culinary school you'll get hours and hours devoted to doing conversions.

The thing you really need to remember is that every substance has a different density. A cup of sugar and a cup of honey don't hold the same weight...
