Add water to one of the pots and bring it to a boil.

While you wait for the water to boil, in the second pot add the butter and warm up on medium heat on the stovetop.

Once the butter starts bubbling and turns a slightly brown colour add the flour and whisk well until smooth. Cook for 3-4 minutes to let the mixture turn a golden brown.

Add the milk and stirring constantly. You don’t want to bring it to a boil, you just want to maintain a high enough heat to melt everything. Keep stirring until the liquid begins to thicken, about 5 minutes or so.

In the meantime, the water should be boiling. Add the macaroni and stir occasionally to prevent the noodles from sticking. Cook according to package instructions. The macaroni I use takes about 8 minutes to cook.

Once the sauce begins to thicken add the cheddar cheese and stir until melted. About 1 minute.

Add the parmesan and stir until fully melted and the sauce is smooth. Another 1-2 minutes. Remove the sauce from the burner.

Drain the macaroni and put it back in its pot. Add cheese sauce to the macaroni a bit at a time until you reach your desired consistency.
