Blend the defrosted and drained spinach (or fresh) with lemon juice and oil.
150 g spinach, 5 tablespoons lemon juice, 100 ml oil
Beat the eggs with sugar until fluffy.
3 eggs, 100 g sugar
Add the blended spinach to them and mix briefly.
Mix the flour with baking powder and add in portions to the dough - mix briefly (the dough will be quite thick - to hold the nuts - but if it seems too thick, you can add a little milk to it).
300 g wheat flour, 1 teaspoon baking powder
Finally, add the chopped walnuts and orange peel and mix with a spoon.
80 g walnuts, 50 g candied orange peel
Transfer the dough to a loaf pan about 30 cm long.
Bake at 170 degrees (convection mode) for about 45-50 minutes - until a dry skewer comes out clean.
After baking, remove from the mold and cool.
Prepare the glaze - mix powdered sugar with a few tablespoons of milk and pour over the cake.
