Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove, adding a splash of milk if needed to restore consistency.
Substitutions: Use vegetable stock for a vegetarian version. Any lager or ale works well; avoid IPAs as they may make the soup bitter.
Tips: For smoother soup, grate your own cheddar cheese rather than using pre-shredded, which often contains anti-caking agents.
Variations: Add cooked bacon bits or sausage for extra protein.
