* I recommend shredding the cheese yourself as pre-packaged shredded cheese contains an additive to keep it from caking.
* For gluten-free flour I use
Cup4Cup Multipurpose Flour.
* If you can't find an English Pale Ale, use any medium bodied ale. You can also use a gluten-free beer in this recipe.
* If after you’ve added the cheese you find the sauce to be too thin, sprinkle a teaspoon of flour over sauce and whisk continuously until incorporated. You may need to add 2 or 3 additional teaspoons.
