Whisk in the roasted red pepper until it's all mixed together and then continue to whisk as you slowly pour in the milk and cream.
1 Cup Milk, 1 Cup Heavy Cream
Once the mixture is smooth add the salt, pepper, nutmeg and cheeses.

Notes
Shredding the cheese with the extra small holes on your grater will produce a creamier sauce.Macaroni and cheese can be made ahead of time and placed in a baking dish.It should be cooled completely, covered and stored in the refrigerator for up to 2 days before baking.
