This is not your ordinary Rarebit..but it is so good..I have made it several times; you can add more mushrooms if you like ,you can add fresh ones or wild ones or those in a can, drained. You can add or delete any of the vegetables and add you favorite....sometimes I add salad shrimp, diced fine,or cooked chicken or leftover grilled beef....it's all good and a real treat for family and friends....we love it!
Using a heavy bottomed skillet over medium heat, melt the butter then add the mushrooms, celery,onion,pepper,water chestnuts and garlic and cook until tender.
Remove skillet from heat. Blend in the corn starch mixed with a little of the cup of beer, mustard, worcestershire, thyme. Return to medium heat.
Now add the remainder of the cup of beer and the pieces of cream cheese and stir and cook until thickened and bubbly.
Gradually add the cheese; cook and stir until the cheese has melted; if necessary add some of the beer reserved in the can to thin the sauce if necessary--otherwise drink the remainder.
Serve hot over toasted pumpernickel, toast points,English muffins or timbales...Enjoy!
