Hungarian walnut
cake deserves to be preserved. Yet it is
often mistaken with another famous Hungarian confection, the five
layered Eszterházy. In the end, there are many claims to being an Eszterházy or walnut cake, but most often these
cakes are a synthesis of two distinctly different cakes. The original walnut
cake was made with cooked buttercream, but nevertheless it was a buttercream and
not a custard filling. The other confusing element is what nuts to use. The Esztreházy is
a torte made with finely ground almonds. The walnut cake is made with finely
ground walnuts. Walnut cake is three layers while the Esztreházy is five. Plus
neither contains chocolate in the cake or in the buttercream.
Internet recipes sometimes advise to roast the walnuts before grinding. Almonds and hazelnuts are fine, but roasting walnuts is a bad idea. Don’t do it because you won’t be able to sleep at night. There must be a chemical change in roasted walnuts and remember you are using a fair amount of walnuts in the cake and in the cream. Interestingly none of my old Hungarian cookbooks advises roasting the walnut meats either. There has to be a reason for this. For grinding up walnuts, you need a food processor or one of those small grinders with the bottle attached.
I suspect bakery walnut cakes have lots of fillers and this allows the lavish decorations on the top. But this homemade version is rich already, so piping rosettes on top would make the cake overly rich. Hungarian walnut cake can also be the base for Sarokház.HUNGARIAN WALNUT CAKE
