Presented as published in 1932. Historical recipes may not meet modern food-safety standards. Cook from the modern interpretation, not the original instructions.
Roll the dough between boards yi or y% inch in thickness, tacked to a bread board, so that all the doughnuts will be the same thickness. Each group should use cutters that have the same diameter. If the dough is divided into 2 parts and each half rolled in part of the flour and shaped into a long roll before placing between the boards it facilitates ease of handling. There should be 3 doughnuts from each part of the dough and 6 for each experiment. In cooking, the doughnuts should be turned when half of the time allowed for cooking is gone. When the time is up, lift each doughnut quickly from the fat onto a skewer held over the kettle so that the fat will drain back into the kettle. The doughnuts should be turned and taken out in the same order they are put into the fat. DOUGHNUTS 577 Weigh the kettle of fat before and after cooking the doughnuts for each experiment. The loss of weight of kettle of fat is the amount of fat absorbed by the doughnuts. Weigh the doughnuts before and after cooking if the per- centage of fat absorbed is to be calculated. The percentage of fat in the cooked doughnuts may be determined by analysis, but this requires too long a time for class results. The percentage of fat absorbed may be based on the weight of the cooked doughnuts or on the weight of the uncooked doughnuts. Denton has suggested that the former is preferable, and this method has been used in calculating the results given in the tables. A. To determine the best proportion of flour to use. The proportion of flour to produce a tender doughnut of good texture varies with different brands and kinds of flour. Therefore, it will be necessary to determine the best proportion for the kind and brand that you use; this pro- portion is to be used in the following experiments. With some flours it will be necessary to start with 5j4 cups or 6 cups of flour instead of 5^^ cups. The dough should be soft and light but not too sticky. If desired, two series of experiments may be run, using bread flour in one and soft-wheat flour in the other. Prepare ^ of the recipe, reserving 1 tablespoon of flour for the board. Mix the dough 80 strokes with a wooden spoon. Follow directions for rolling and cutting. Cook the 6 doughnuts for 3 minutes at 175° to 180°C. (345° to 355°F.). 1. Use 5y2 cups of flour (616 grams) for the full recipe. 2. Use 5}i cups of flour (588 grams) for the full recipe. 3. Use 5 cups of flour (560 grams) for the full recipe. 4. Use 4}i cups of flour (532 grams) for the full recipe. B. To determine the effect of extent of mixing upon tenderness, texture, and fat absorption of doughnuts. 1. Prepare the full recipe, reserving 4 tablespoons of flour for rolling. Use the proportion of flour found best under A. Mix a total of 40 strokes with a wooden spoon. Observe and record any changes in the dough during mixing. Remove approximately 54 of the dough (about 280 grams). Follow directions for rolling. Cook the 6 doughnuts for 3 minutes at 175° to 180°C. Use the remaining dough in the following experiments. 2. Mix the remaining dough from Bl a total of 60 strokes and remove approximately 280 grams. Proceed as in Bl. 3. Mix the remaining dough from B2 a total of 80 strokes. Remove approxi- mately 280 grams. Proceed as in Bl. 4. Mix the remaining dough from B3 a total of 100 strokes. Proceed as in Bl. Weight of dough-
