3. Use 1 egg, 1 cup of distilled water, 2 tablespoons of sugar. Bake until the temperature at which D2 sets is reached. Remove from the oven and add Yi teaspoon of calcium lactate that has been moistened in a tablespoon of distilled water. Stir. What happens? 4. To 1 egg, 1 cup of distilled water, 2 tablespoons of sugar, add about 1/16 teaspoon or less of aluminum or ferric chloride. Mix the ferric or aluminum chloride with the distilled water ; then add the beaten egg and the sugar. What happens when the egg is stirred in the mixture? Continue stirring for a few seconds. 5. Repeat El, but add ^ teaspoon of aluminum or ferric chloride. Does the custard coagulate during cooking? Test the custards with litmus paper. 6. To 1 egg, 1 cup of distilled water, and 2 tablespoons of sugar, add 34 teaspoon of salt. 7. Repeat E6, but omit the salt and add Yz teaspoon of a milk-salt mixture used in feeding rats. 8. To 1 egg, 1 cup of distilled water, and 2 tablespoons of sugar, add ^ teaspoon of lemon juice. 9. To 1 egg, 1 cup of distilled water, and 2 tablespoons of sugar, add 1 teaspoon of lemon juice. F. To determine the effect of beating on thickening power of the egg. 1. Use 2Y2 eggs. Beat in a bowl either by hand or with an electric mixer until the yolks and whites are well blended. Weigh out 48 grams and combine with 1 cup of milk and 2 tablespoons of sugar. 2. Beat the egg remaining from part Fl until thoroughly beaten. The egg can be beaten as long a period as desired. Weigh 48 grams of the egg. Discard the remaining egg. Combine the 48 grams with 1 cup of milk and 2 table- spoons of sugar. If the egg was beaten with an electric mixer, put milk in the mixer bowl and combine with the mixer. Does the egg tend to float on top of the milk? Bake according to directions under B. 3. Beat 1 egg slightly, so that the yolk and white are not well blended. Add to 1 cup of milk and 2 tablespoons of sugar. What is the effect of increasing the egg upon temperature of coagulation? Of varying the proportion of sugar? Does the distilled-water custard set? What is the effect of adding calcium lactate? Salt? What is the reaction of the custard containing the small proportion of aluminum or ferric chloride? The one with the larger proportion? Does either set? Unless the proportion of ferric or aluminum chloride is small enough, E4 may not set. Time of cooking Coagulation temperature Texture Fh Comments Results and conclusions. G. Soft custards. The series under C and D may be repeated and cooked as soft custards, or the baked custards may be omitted and the soft custards prepared instead. Prepare once the recipe and follow directions under A for cooking. 382 EGG COOKERY Salad Dressings Experiment 65. To determine the effect of acid upon coagulation of egg in cooked salad dressings. Recipe : Egg yolks 4 72.0 grams Sugar y2 tablespoon 6.2 grams Liquid total 1 cup 240.0 grams Mustard >^ teaspoon Salt yi teaspoon A. Cook in a double boiler. Follow directions under Experiment 64A for cooking. It is not necessary to cook as slowly as under Experiment 64A, but the time for each degree rise in temperature should be the same in all the experiments. Remove portions of the salad dressing at the following temperatures: 76°, 78°, 80°, 82°, 85°, and 92°C. Note the temperature when the salad dressing coats the spoon,
