Seriously... The Cupboard's Lemon Icebox Pie and their Lemon Meringue Pie are truly different pies. That's really all I was indicating.
Interestingly enough, the recipe - at least the one in their cookbook - for their Lemon Icebox Pie does not call for cooking of the eggs. Hmm... -Ah, for the days of pre-salmonella scares.
And, yes, I know, technically speaking, that Hollandaise, Bernaise, and the other "spin-off" sauces are also technically custards.
