Chinese chicken salad often presume a bound salad with chopped vegetables and mayonnaise, typically without lettuce. For example, "The Settlement Cookbook" by Mrs. Simon Kander, published as early as 1910, includes a simple "Lettuce salad" with chopped onion and French or German dressing; but, no Chinese, Asian or Oriental salad of any kind. Similar bound chicken salads were found in "Joy of Cooking" as of the 1974 editions (first published as of 1931). It was by 1950s that main course type salads started to appear in books like "Better Homes & Gardens, New Cook Book"; whereas, that often included Caesar salad along with
Unbalanced Oil and Vinegar "split" the message to acceptable pieces formula_17. Then the equations have to be built. Every single equation has the same form: The next steps sign a given message formula_8 and the result is a valid signature formula_20. The vinegar and oil variables build the pre-signature formula_24. Finally formula_25 gets transformed by the private transformation formula_5 to give the valid signature formula_27. The system of equations becomes linear if the vinegar variables are fixed – no oil variable is multiplied with another oil variable in the equation. Therefore, the oil variables can be computed easily using, for example, a Gaussian reduction
