Step 1

Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally, until tender yet firm to the bite, about 8 minutes.

Step 2

Meanwhile, melt butter in a saucepan over medium heat. Stir in flour until mixture is smooth. Slowly add half-and-half, whisking as it is poured in. Stir until sauce thickens slightly, about 3 minutes. Add Cheddar cheese, salt, Worcestershire sauce, mustard, pepper, and turmeric; whisk to combine.

Step 3

Drain macaroni and add to the cheese sauce. Stir until evenly coated.
