Question: is gouda good for grilled cheese?
Answer: Cheeses with an acidity in the range of pH 5.3 to 5.5 — such as gouda, gruyére or manchego — are best for being heated up in a sandwich. When cheeses have a lower pH, aka when they're “sharper,” they break down more easily, resulting in clumps that are apt to ruin your perfect grilled cheese experience.
