Argh help!!!

Back, I don't know, 10 years ago... Mum used to order Veal Scallopini with Garlic Sauce from La Porchetta... The garlic sauce was TDF and I am desperate to make it. I can't get onto my mum and need to get dinner on soon.

If I were to just brown some onion, garlic and then add cream and simmer until it reduces, would that work? I was then going to cover the veal and pop in the oven until DF gets home
