Given the background description of some cooking related query, summarize the question into a title

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.

I'd like to try my hand at baking my own bread. Do I need a bread maker to get decent bread? Are there any advantages to using a bread maker vs. my normal oven?

I am considering ordering a few silicone kitchen utensils from China (like this). However, I am concerned about their food safety. The seller assures that the tools are made of "100% Food Grade Silicone" and food safe symbol (fork and wine glass icon) is there - however anyone can print anything on their products... The seller also assures that their products are certified by a number of agencies ("CIQ,EEC,FDA,LFGB,CE / EU,SGS", of which for certain I can recognize only FDA, EU may possibly mean European Union).Do you have any experiences with this producer or is there any official online resource (e.g. published by FDA or EU) that can be used to confirm food safety of products offered by a given producer?
