Alfredo Sauce for 50
This recipe makes about 50 servings, so when serving 150 or 200, make 3 or 4 separate batches.
It is just too difficult to make a successful Alfredo sauce in one large batch.
1 lb. butter
10 cloves garlic, minced
1 lb. flour (approx. 4 cups, depending on humidity, maybe slightly less)
2 litres heavy cream (whipping cream)
1 liltre whole milk
1 ½ lb. freshly grated parmesan cheese
Fresh black pepper to taste
Melt butter in a 40 litre pot. Add garlic, and sauté for 1 minute, then stir in 1 lb flour to make a roux.
Slowly pour in 3 litres heavy cream and 1 litre whole milk and stir with a whisk until sauce begins to thicken.
Add 1-1/2 lbs freshly grated parmesan cheese and stir well. Add fresh cracked black pepper to taste and
test for salt.
