WOW!
Another great session with Sarelle in our Israel Branch last Sunday night in Modiin! We Nine participants shared in our acclaimed "Eggs and Meringues, Artistically and Scientifically!
From all accounts, we all had a grand time learning from and working with Sarelle as she helped prepare us for the upcoming Pesach Holiday with an information and technique packed two and half hours all about tasty and beautiful kosher for Passover pastries.
In addition, we learned how to destroy the potential for salmonella without scrambling our yolks; temperature, structure, emulsifers, proteins, starches, ph and more. All the while, Sarelle shared her amazing professional techniques with us making the complex look easy! We learned piping, whipping egg whites, different types of meringues, how to make delicate French Macarons and fill cookies, use of a double boiler, how custards congeal, starch based and non-starch based custards!
Stay tuned for upcoming programs!
The Kitchen Science program of the Martin and Gertrude Walder Science Laboratory and Learning Center turns your kitchen into a science laboratory where you can study cooking and baking reactions and learn about the wonderful world of science and math while cooking up scrumptious dishes and pastries! It's the difference between amateur and export products. Culinary with an educational purpose! See us on facebook.com/WalderKS

Salt and Cream of Tartar affecting foaming of egg whites during whipping

Salt increases the
whipping time of the egg whites and decreases the stability of the foam. This
is because salt dissolves into positive and negative ions. These ions bond with
proteins, which disrupts the foam from forming. To protect the foam, salt is
normally added after the whites have been beaten to the foamy stage.
Acids (vinegar, lemon
juice, cream of tartar,etc) are also added after the foamy
stage has been reached because they delay foam formation. Acids are useful
because they stabilize the foam. Acids decrease the pH, which reduces the
ability of the proteins to coagulate.
Cream of tartar:
Potassium bitartrate, also known as
potassium hydrogen tartrate, with formula KC4H5O6, is a byproduct of winemaking.
