PROBLEM: My wife's chicken cake recipe calls for mayonnaise as one of the batter ingredients. In my opinion, mayonnaise is completely unsuitable for high-temperature processing (as in baking), but I was unable to come up with a substitute for it.So, my question is, what can we put into cake batter instead of mayonnaise?Update: I think mayonnaise is unsuitable for baking because it is an emulsion which separates into its ingredients when heated, emulsifying agents used in a commercial mayo are not particularly healthy, and mayonnaise does not taste any good when it is broken into its components.The components of the batter are: 6 table spoons of flour, 3 eggs, 200gram mayo, 200gram sour cream. The components of the filling are: chopped prepared chicken meat, chopped sauteed onions, boiled eggs, etc.

SOLUTION: Mayonnaise substitute in cake batter

PROBLEM: My attempts at Meringue-making are driving me a tiny but crazy...No matter what I do, at first, they are still wet on the inside, and if I leave them standing longer to dry out, they get a chewy/gummy-like consistency when bitten into (this is really the best way I can explain it).I am currently working with 50-60 grams of granulated sugar per eggwhite (depending on what size of egg I have), a slightly heaped teaspoon (not the measuring-kind, just a regular, european teaspoon) of cornstarch per eggwhite.I add a pinch of salt to my eggwhites before whipping them up, then slowly add the sugar. Temperature-variation of the eggwhites did not seem to do much about the chewiness-Problem.I have tried drying between 70 and 100 decrees Celsius (most recipes seem to call for 80).How do I get them to dry all the way through without burning them? I SUSPECT the fact that I seem unable to get them all dried out is the actual problem!EDIT: For size: I usually strongly heap a teaspoon (mostly because the whole issue with a piping bag seems futile to me if the texture does strange things anyway...). They are not overly large, I'd say, and I even have the chewyness-issue when I make very very flat ones.

SOLUTION:
How to prevent Meringue from turning chewy/gummy-like?
