More baking science…..sugar!

Sugar, sugar….oh, honey, honey…..(anyone else hear the Archie’s song?) Here’s the link to help you get in the mood.  http://youtu.be/h9nE2spOw_o

Another of our How Baking Works lessons focuses on sweeteners, where we examine different classes of sugars: crystalline, syrups and specialty sweeteners.  Crystalline sugars encompass everything from granulated sugar, to brown sugar and powdered sugar, as well as Demerara, Turbinado and Muscavado.  For syrups, we include corn syrup, glucose, molasses, honey and of course (my favorite!) maple syrup.  Specialty sweeteners comprise a variety of products including high intensity sweeteners (such as Splenda and Stevia), dextrose and isomalt .

And yes, we taste them ALL!  You would be surprised at the different flavors that these sweeteners impart.

In addition to identification and tasting, we also conduct a few basic experiments.  One experiment explores the functions of sugar by adjusting the amount of this ingredient in a basic pound cake.  We bake a control pound cake using the correct amount of sugar (100%) and then we bake other pound cakes (the variables) using the following percentages of the correct amount:  0%, 25%, 50%, 150% and 200%.  This experiment proves some of the functions of sugar.  In addition to the obvious function of “sweetening,”  granulated sugar also:  provides tenderness, moistness, aids in leavening and provides color (caramelization).  And yes, we tasted all of these too!

Here's a comparison of cakes made just with Splenda or Stevia, and cakes made with a 50/50 blend of sugar and one of these sweeteners.

Here’s a comparison of cakes made just with Splenda or Stevia, and cakes made with a 50/50 blend of sugar and one of these artificial sweeteners.

For this experiment with “high-intensity” sweeteners.  We made the pound cakes with either Splenda or Stevia, and then with a 50/50 blend of Splenda/granulated sugar or Stevia/granulated sugar.  Our findings here proved that high-intensity (or artificial) sweeteners can only provide “sweetness” to a product.  When used as the sole sugar replacement, none of the other functions existed.  Note:  no color, tenderness, moistness or leavening.  Of course, we tasted them and concluded that the blends were much more appetizing.

Cookies made with no sugar, the correct amount of sugar, and double the amount of sugar.

Another experiment explored the functions of sugars in relation to the baking of cookies.  For this project, we made cookies with 0% sugar, 100% sugar (the correct one) and 200% sugar.  You can see here how the amount of sugar affects the caramelization, texture and the spread of the cookie.  Taste?  Yes, you guessed it!  Hmm…..by this time, as you can imagine, we are all pretty tired of sweets!  (Education and learning require perseverance!)

So, did you know that sugar has functions other than sweetening?

Creativity: Food as Art, Art as Food

In food education, we name the programs of study:  Culinary Arts.   The two-year degree though is called an Associates of Applied Science.  So how do we make the connection between “art” and “science?”  Often, people say that cooking is an art, while baking is a science.  What makes this distinction?  Do the two overlap?  YES!!!

When cooking, measurements are not always crucial to the final product.  A recipe may have the following instructions:  a clove of garlic, a bunch of chives, two chicken breasts and “season to taste.”  The exact measurements are not indicated as it is up to the chef to determine the amounts, according to the desired result of the final creation.  An experienced chef can estimate the proper proportions and predict the outcomes.  Therein lies the art of taste!  How these creations are assembled on the plate then requires the art of presentation.

During one of the “chapters” in my professional career, I worked as the first mate and cook on a private yacht.  The owner of the boat, an attorney, and his wife, a classically trained chef, went out to different restaurants for dinner six nights of the week.  On the seventh night, I cooked for them on the boat.  Why did they eat out so much? They believed in the art and entertainment of the dining experience.  They would examine every component of the meal:  how the hostess greeted them, the décor of the restaurant, the eloquence of their waiter, the font of the menu, the feel of the cutlery and the design of the china, and oh yes, the meal itself!  The food, though an important part of the meal, was not the only creative medium in the art of dining.  The choreography of the entire evening involved many interdependent components.  When dining out, how often do we think the food was good, but the atmosphere made the meal less enjoyable?

In the baking and pastry world, we follow formulas.  We think of a recipe as a list of ingredients, whereas a formula determines the exact amount of each ingredient with a specific method of preparation (MOP).  As we “eat with our eyes first,” initial appreciation of a product relies upon the presentation.  We value wedding cakes for their beauty, birthday cakes for their whimsy and sometimes we create sculptures of food for their visual appeal alone.  Although the eating of the creation may be a secondary desire, taste completes the experience.  So although the ratio of ingredients and the method in which the product is prepared can be considered a science, the art depends on the visual appeal.

I find joy in trying a new recipe, or adapting an old recipe by using the ingredients at hand, making substitutions to accommodate the tastes of whom I am feeding.  For baking, I make a rule of following the initial formula as indicated.  Then, through my knowledge of baking science (more on that next week!), I may make adjustments to please my palate or alter the texture.  When making wedding or birthday cakes, I spend more time at the drawing board, then the actual production of the creation.  These are just some of the creative aspects of the food world.

The photos included in this post offer a variety of artistic views of food.  Food art can be everything from the natural beauty of fresh picked strawberries, to sugar and chocolate showpieces, to a sculpture of the world’s largest lobster. You can decide, is it art?

How do you “create art” in the culinary realm?
