Separate 4 eggs into yolks and whites; leave the other 4 eggs whole.
Beat the icing sugar with the 4 egg yolks and the 4 whole eggs until fluffy, about 20-30 minutes with a mixer (or half an hour by hand).
Mix in the scalded, chopped pistachios, the candied lemon peel, and the coarsely crushed and finely chopped almonds.
Whisk the reserved 4 egg whites to stiff peaks and gently fold into the batter.
Pour into a buttered, floured cake tin, and bake slowly (160°C) for about 50-60 minutes.
For the glaze, cook the sugar with a little water into a thick syrup, remove from heat, stir in the lemon or orange juice, and whisk constantly while cooling until thick.
Coat the cooled cake with the glaze.
