The present invention relates to baking mixes.
Short-crust pastry dough is a fat rich, low water baking dough. The high fat and low water content of the dough, in addition to shortening mixing time, also reduces the development of gluten networks and produces a crisp, crumbling pastry. Such dough is used in kitchens throughout the world to produce diverse baked items such as pie crusts, cookies, tarts and quiches.
Instant baked goods mixes have existed for over 60 years. Such mixes, requiring the baker to add only water, or in some cases, water and eggs or fat, simplify the baking process while also cutting the preparation time and increasing the uniformity of the baked good. Nevertheless, most such mixes produce a low or medium fat final product due to the difficulty in integrating large quantities of fat into a dry, pourable mix. A short crust pastry dough mix requires a high percentage of dry fat that can be integrated uniformly into a pourable mix, while also retaining a pleasing butter-like flavor. Such a mix, that consistently provides a crisp, crumbling, buttery pastry when baked is still needed.
The present invention provides mixtures comprising white flour, spray dried powdered palm fat and salt, a method of producing dough from those mixes, and the dough so produced.
According to the first aspect, there is provided a mixture comprising: flour, spray-dried powdered palm fat, and salt, wherein the flour and the fat are in a proportion that ranges from 100:45-55 by weight.

Additionally, each of the various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below finds experimental support in the following examples.
Various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below find experimental support in the following examples.
Various experimental mixtures were tried in an effort to produce a dry, pourable powder that when mixed with liquid and then baked produces a pleasing short-crust pastry. Mixtures were judged based on the ease of mixing all the ingredients, ability to produce a dry pourable powder, and the appearance and taste of the final pastry. As with most baked goods, flour was the primary ingredient. Soft white wheat flour was selected as the flour to be used, due to its low gluten content which will produce a crisp and flaky product when baked. Use of hard flour (high gluten) resulted in development of an extensive gluten network, and puffing during baking. Each experimental sample was based on 150 grams of flour, and all other ingredients were measured relative to the flour by weight.
Sugar was not required for producing a mix that produced crisp and flaky pastry. However, for sweet pastries it is essential. Use of granulated sugar caused a sandy feeling in the mouth, as low moisture levels in the dough resulted in sugar crystals that did not dissolve. Castor sugar was used instead and produced no such negative texture. 50 grams of castor sugar per 150 grams of flour was found to be ideal for sweet dough, although more or less can be used depending on the desired sweetness in the final pastry. For a salty dough, such as might be used for quiches, no sugar was added.
Salt was required for producing proper taste in the dough, however, less salt was required when sugar was added. By trial and error, it was found that 1.2 grams of salt for sweet dough, and 2.5 grams for sugarless dough were ideal. However, once again, the mount of salt could be varied as required by the specific taste preference of the baker.
Different types of fats were tried in order to determine the best option.
Standard short-crust dough is made with butter. Butter consists of ˜80% fat and ˜20% water and milk solids. Butter's melting point is ˜30 degrees Celsius, which illustrates the two main constrains on the fat used in pastry:
To help with this second constraint, short-crust dough should generally be refrigerated before handling in order to keep it solid. Pastry made with butter is very brittle. This allows it to be chewed easily, with no hard areas, and to break into small granules that melt in the mouth, all while the center of the dough is well baked.
Butter usage in standard short-crust dough is 100 grams of butter to 150 grams flour. Since butter is only ˜80% fat this is equivalent to 80 grams of fat to 150 grams of flour. Butter cannot be used in producing a dry pourable mix, as it contains ˜20% liquid and also would go rancid if stored without refrigeration.
Margarine is designed to mimic butter in baking and thus was tested as a possible fat in short-crust dough. Margarine remains solid at room temperature resulting in easier workability than butter, but still melts in the mouth while eating. However, overall, pastry made with margarine was worse than pastry made with butter, and required more chewing in order to break it into granules. Margarine, like butter, contains 80% fat and therefore 100 grams was used for 150 grams of flour. Margarine had similar problems being integrated into a dry pourable mix.
High melting point palm fat, called stearin, is the solid fraction of palm oil, and is solid at room temperature. Stearin in a solid brick form did not produce dough under normal conditions, as it was too hard to mix in a standard mixer. Stearin in semi-powder form could be incorporated into dough, however it still retained a bead-like particulate form in the dough, and during baking a fraction of it melted out of the dough and left pores in the pastry. Further, the resulting pastry was very hard and unchewable, and very pale in color. In addition, due to the high melting point of stearin (above body temperature), the fat did not melt well in the mouth and left a very unpleasant, waxy feeling.
Refined palm oil has a melting point close to, but slightly below, butter. At room temperature, it can be either a soft solid or liquid, depending on the precise ambient temperature. As palm oil contains 100% fat, 80 grams were used per 150 grams of flour. An additional 20 grams of water was added at the time of liquid addition. The result was a good dough which was very similar to that produced with butter, with a good mouth feel and texture. However, since palm oil is semi solid to liquid at room temperature, it was very difficult to incorporate it with flour to create a dry pourable mix in the lab.
Powdered butter, which is butter dried up into a pourable powder, was tested as a substitute to semi-liquid fat. Powdered butter is composed of 80% butter fat and 20% stabilizers (mostly milk proteins and maltodextrins). A preliminary test was conducted and even though powdered butter contains the same amount of fat as butter (per 100 grams), it was concluded that its low moisture level (˜0% instead of 20% in butter) required the usage of the same weight of powdered butter as regular butter and addition of extra water at the time of liquid addition. Powdered butter produced pastry that was harder and less crumbly then butter pastry, with a soft unbaked center, and was much darker in color.
Finally, a spray-dried powdered palm fat was tested. The powder contained 80% refined palm oil and 20% stabilizers. The use of powdered oil made it possible to dry-mix the product to create a dry pourable mixture. The resulting pastry was comparable to that produced with palm oil or butter, being a soft, easy to chew, crumbling pastry that melted in the mouth without a residual waxy feeling. Additionally, dough handling was better than butter-dough, as it was more flexible and required less refrigeration; nevertheless, best results still required some cooling of the dough. As the fat content in the powdered palm fat was comparable to powdered butter, it was hypothesized that 100 grams might be needed per 150 grams of flour. However, experiments showed that 80 grams worked well and amounts as low as 70 grams could still produce good pastry. 75 grams was found to be ideal as it allowed for better pricing and quality margins. In addition, mixtures with powdered palm fat were tested for accelerated shelf life and showed no sign of oxidation or rancidity.
During the testing of various fats, it became clear that a correct moisture level in the dough is crucial for creating a good final pastry. Too low a quantity of added liquids resulted in a dough that did not combine and could not be further processed; while too much liquid resulted in a pastry that was not flaky and crumbly, and that did not bake evenly.
The ideal amount of liquid was determined to be around 40 grams of water to 150 grams of flour. Recipes using butter generally call for 50 grams of total liquid (30 grams of liquid added, plus 20 grams from the butter itself), which theoretically would necessitate 50 grams of liquid when using powdered palm fat (which contains no water). However, empirical testing found the actual best amount of water was lower than theorized.
Samples of the mixture were sent to outside patisserie experts for cross determination of ideal liquid amounts for 300 grams of final mix (the amount needed for one medium tart/quiche). It was found that different amounts of liquid were required depending on whether sugar was present in the dough. Since sugar can account for a large portion of the weight of the mix, mixtures without sugar have more flour by weight and thus require more liquid. For sweet pastry, the ideal amount of water was found to be 47 grams for 300 grams of mix. For salty pastry (with no or little sugar), the ideal amount of water was found to be 53.5 grams for 300 grams of mix.
Interestingly, it was found that using whipping cream (38% fat for dairy cream or 20% fat for non-dairy cream) in place of water produced even better flavor results. In the case of whipping cream, 60 grams per 250 grams sweet mix and 80 grams per 250 grams salty mix were found to be ideal. Use of cream was recommended for best results, while water gives adequate results for basic recipes.
Usage of eggs, whether whole or just yolks, did not produce palatable pastry. Similarly, use of milk was not advantageous in comparison to water.
