They're easy to make, but just a little messy (this batter is epically sticky).
- 425g almond meal
- 250g icing sugar
- zest of 2 oranges (make sure they're nice & firm)
- 1/2 tsp almond essence
- 1/2 tsp cinnamon
- 1 egg
- 3 egg whites
Preheat oven to 180C and line two baking trays (ones you'd use for biscuits).
Combine almond meal, icing sugar, zest, essence and spice in a mixing bowl. Beat together the whole egg & egg whites in a jug (just to combine, no real aeration is needed). Make a well in the centre of your dry ingredients and pour in the egg. Use your hands to mix - they're only going to get messy anyway!
Break off walnut-sized pieces of mixture (about a tablespoonful for those unaccustomed with whole walnuts) and roll into little balls. Place on your baking trays (about 3-5cm apart, they don't really grow).
I found (and Nigella suggested) that if you rinse your hands frequently under cold water to remove excess mixture you'll have a far easier time of it. A pain I know, but these little delights are well worth the effort.
Cook in the oven for 20 minutes until lightly golden. Cool on a wire rack before gobbling up.
