I have cooked this classic recipe a few times with good results. However, the one time I tried to do a larger batch something went wrong. So, I was hoping some of you might help with how to scale the recipe up. I'm assuming that simply doubling or tripling or whatever every single ingredient is not quite right. But I'm not confident in judging what to increase and what to leave alone or only increase partially. I'm hoping a better cook than I can give me some help.
I've copied the recipe below (I'm assuming this is ok to do as the recipe is very widely available all over the internet). This is from the original, first MH book, not the later compilation
2 tablespoons chopped yellow onion
3 tablespoons olive oil
3 tablespoons butter
2 tablespoons chopped celery
2 tablespoons chopped carrot
0.75 lb ground lean beef, preferably chuck
1 cup dry white wine
0.5 cup milk
1/8 teaspoon nutmeg
2 cups canned italian tomatoes
yield: 2.25 cups
So my question is what might you suggest for, say a double or triple batch. And then, if anyone wants to venture an answer for an even larger batch, how bout 10x for a large party?
Thank you so much for the help. It is much appreciated.
