Welsh Rarebit

The cheese paste can be prepared up to 2 hours ahead and kept at room temperature, covered with plastic wrap pressed directly against the surface to prevent drying. Stir well before spreading. Do not refrigerate, as cold paste will be too stiff to spread evenly.

Welsh Rarebit is best served immediately after baking. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days, but the toast will lose its crispness. Reheat in a 350°F oven for 8-10 minutes; do not microwave, as this will make the toast rubbery.
