milk - Substitute with unsweetened almond milk: Unsweetened almond milk can be used for a dairy-free option, though it may slightly alter the flavor.
sharp cheddar cheese - Substitute with gruyere cheese: Gruyere cheese melts well and has a rich, nutty flavor that complements the dish.
dijon mustard - Substitute with yellow mustard: Yellow mustard can be used in a pinch, though it has a milder flavor compared to dijon.

How to Store or Freeze This Dish
Allow the cheese sauce to cool completely before storing. This prevents condensation, which can make the sauce watery.
Transfer the cooled cheese sauce into an airtight container. Make sure to leave a little space at the top to allow for expansion if freezing.
Store the cheese sauce in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, stirring frequently to maintain its creamy texture.
For longer storage, freeze the cheese sauce. Label the container with the date to keep track of its freshness.
To freeze, pour the cheese sauce into a freezer-safe container or a heavy-duty freezer bag. Squeeze out as much air as possible before sealing.
When ready to use, thaw the cheese sauce in the refrigerator overnight. Reheat gently on the stove, adding a splash of milk if needed to restore its creamy consistency.
For the toasted bread, it's best to toast fresh slices when ready to serve. However, if you must store it, keep the toasted bread in an airtight container at room temperature for up to 1 day.
Avoid freezing the toasted bread as it can become soggy upon thawing. Instead, toast fresh slices and top with reheated cheese sauce for the best texture and flavor.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Welsh rarebit on a baking sheet. Cover it loosely with aluminum foil to prevent the cheese sauce from drying out. Bake for about 10-15 minutes or until heated through.
Alternatively, use a toaster oven. Set it to 350°F (175°C) and place the rarebit on the rack. Heat for about 10 minutes, checking occasionally to ensure the cheese doesn't burn.
For a quicker method, use the microwave. Place the rarebit on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to trap moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you have a stovetop griddle or skillet, you can reheat the rarebit there. Preheat the skillet over medium-low heat. Place the rarebit on the skillet and cover it with a lid. Heat for about 5 minutes, flipping halfway through to ensure both sides are warmed.
For a gourmet touch, use a broiler. Preheat your broiler on low. Place the rarebit on a broiler-safe pan. Broil for 2-3 minutes, watching closely to prevent burning, until the cheese sauce is bubbly and slightly browned.
