since w brought up the first contemperary cooked egg yolk mousse, here is pate a bombe, a component of mousse, butter cream and sauces including ice cream and other confections.
egg yolks whipped with boiled sugar poured in to create something like the opposite of italian meringue.
it is light yellow in colour, the consistancy of fluff, can be kept frozen, is cooked so no worry of biological contamination, can be measured into formulas.
it is wonderful to use in mousses and adds a richness to ice cream that boarders on the sublime.
please post your yolk secrets..........
