At which temperature is the most desirable texture for a salad dressing obtained with the different proportions of acid? Which proportions of acid give the thicker salad dressing? Does curdling occur at the higher temperatures? From results with custard, what would be the result of increasing the propor- tion of salt? Which produces the clearer salad dressing, vinegar or lemon juice? 76° 78^ 80= 82^ 85^ 92" Conclusions. B. To determine the effect of varying the ingredients and the proportion of ingredients in salad dressings. 1. Repeat 65,2, or 65,5, but increase the salt to 1 teaspoon. 2. Repeat Bl, but increase the sugar to 2 tablespoons. 3. Repeat Bl, but substitute 72 grams of whole egg for the ^g^ yolk. 4. Reduce the egg yolk to 36 grams and add 2 tablespoons (14 grams) of flour. OMELETS 383 Hollandaise Sauce / ^^__ Experiment 66 To determine the factors affecting the smoothness of Hollandaise sauce. Recipe : Butter J/2 cup 112 grams Egg yolks 2 36 grams Hot water H cup Vinegar 1 tablespoon Salt }i teaspoon Paprika few grains 1. Melt the butter in the top part of a double boiler. When melted remove from the heat and add the well-beaten egg yolks, stirring until blended with the butter. Add other ingredients and return to the double boiler. Heat slowly and stir continually. Remove samples at the following temperatures, 72°, 74°, 76°, 78°, and 80°C. If mixture has not separated at 80°C., continue to remove samples until curdled. 2. Repeat 1, but do not beat the egg yolks before adding to the butter. 3. Repeat 1, but increase the egg yolks to 4. 4. Repeat 3, but omit the water and increase vinegar to 2 tablespoons. 5. Substitute lemon juice for any of the above. Compare smoothness and consistency of the different sauces. Compare the flavor. Omelets Experiment 67. To determine the factors that affect the texture of omelets. Recipe : Egg 1 Salt }/s teaspoon Liquid 1 tablespoon 15 cc. Butter }4 tablespoon 7 grams Directions for mixing and baking. The first omelets should not be used for comparisons for experiments. The omelets should be made over several times if necessary to acquire the technic and the manipulation necessary to make a good omelet. Separate the white and the yolk of the egg. Beat the yolk until it will mix well when folded in the white. Beat the white until it is frothy and add the liquid; add the salt and continue beating until it is quite stiff. It should be beaten until it will stay in an inverted bowl. Mix the beaten white and yolk by folding. Use a spatula for folding. The spatula should have a flexible blade near the end but should be rigid where it joins the handle. Fold by holding the blade of the spatula parallel to the right side of the bowl. Move to the bottom of the bowl, at the same time pressing so that the spatula scrapes the material from the bottom of the bowl. Bring up with the blade parallel to the left side of the bowl. As the spatula is brought across the top of the material turn it upside down. Turn 384 EGG COOKERY
