Abalone Thermadore is better than Lobster Thermadore, but remember that you must pound them!
Preheat the broiler. Place diced abalone in the boiling water and remove from heat after 1 minute. Let cool slightly and add cream, paprika, celery salt, and Tabasco. Simmer 5 minutes. Spoon out some of the mixture and add to the cornstarch to make a smooth paste. Add this back to the mixture and simmer another 5 minutes. Melt the butter and add to the shredded bread stirring until the butter is absorbed. Place the abalone mixture into a shallow pan (or divide into individual pyrex dishes) and put the bread on top. Place under the broiler until the bread is browned. Salt & pepper to taste.
