This 18th century dish from Great Britain hales from Wales and is made with melted cheddar cheese sauce over toast. Think fondue-like only more of a pub-ish lunch; ideal and comforting during cold weather.
A béchamel or white sauce can be spiced up with a pinch of cayenne pepper, or hot sauce, 1/2 cup IPA (or another good ale), 1 teaspoon prepared English mustard, and pinch of paprika.
Finish the sauce off with 1 cup finely shredded cheddar cheese. Whisk in and simmer just until the cheese is melted. Serve a couple tablespoons of sauce over a slice of good wheat toast. Serve as is, or you may want to place the 'rarebit' under a broiler for 30 seconds to brown lightly. Top with chopped chives or green onion. I've also topped this with a slice of good ripe tomato + sweet onion. Enjoy.
A Light Béchamel Recipe | ChefGeorgeHirsch.com
1 Tablespoon sweet butter
1 Tablespoon flour
1/2 cup half & half (can use milk for a lighter version)
In a small sauce pan over low heat add butter and flour and cook for 2-3 minutes. With a wire whisk add in milk and allow to simmer until slightly thickened.
If using béchamel for rarebit, continue adding ingredients as above and simmer for 5 minutes while continuing to stir.
