Many people rave about the creamy, rich texture and taste of this macaroni and cheese. It is considered a custard consistency, which some may prefer over a traditional creamy version. The cheese is said to be more flavorful when using sharp cheddar and when the eggs are incorporated.
Several people made substitutions, such as using sharp cheddar instead of just cheddar, adding American cheese to help with creaminess, and omitting the eggs for a smoother texture. Others used different types of pasta and cheese blends, including spiral noodles and a mix of Monterey Jack and cheddar.
