Fill a large skillet with deep sides with water about halfway and bring it to a boil on the stove. Salt it generously. Boil the
Lobster Tails (4)
in it for 8-9 minutes, until the shells turn a vivid red. Remove them and let them cool enough to handle.
When you can handle the lobster tails, crack the meat out of the shells and dice it into bite-sized chunks. Drain the water from the skillet you boiled the tails in and put the skillet back on the stove.
Butter (1/4 cup)
in that skillet and add the
Garlic (3 cloves)
. Let it get fragrant for about a minute.
Next, add in the lobster meat and let it cook for a minute or two in the butter and garlic. Remove the lobster to a plate and set it aside.
Add the remaining
Butter (1/3 cup)
All-Purpose Flour (1/3 cup)
to the pan. Whisk them together until they become a thick, golden paste for about a minute.
Slowly pour in the
Milk (3 cups)
while you keep whisking to bring the béchamel sauce base together. Season it with
Salt (to taste)
Ground Nutmeg (1/4 tsp)
. Reduce the heat to low and let it bubble and thicken for 10 minutes, whisking it often.
While the sauce cooks, boil the
Medium Pasta Shells (1 lb)
in another pot of boiling water. Salt the water generously before you do. Once it is tender after 8-10 minutes, drain it.
Gruyère Cheese (1 cup)
Fontina Cheese (1 cup)
Extra Sharp Cheddar Cheese (1 cup)
into the sauce until they melt, then add the lobster meat back in. Finally, add the cooked pasta in and stir everything together thoroughly.
Take the pan off of the heat and serve the mac and cheese immediately!
