They're are slightly pasty looking, so some green food colouring might be a good idea, to give them a pastel hue.
Recipe under the cut:-
100g caster sugar
60g ground almonds
210g plain flour
1 egg (whipped)
1 teaspoon vanilla paste
a handful of pistachio nuts
green food colouring (optional)
preheat oven to 180
mix the margarine and sugar until creamy. (add in food colouring if desired)
add in the ground almonds and stir until well combined. Add in plain flour, and vanilla. your mixture should now resemble dough, if it seems to be too dry (mine was) add in the egg until the mixture is a thick springy dough.
using your hand make small balls, add pistachio nuts to these balls as you go and reshape. I put 4-5 nuts in per biscuit.
place on a baking tray and bake for 10-12 mins.
Enjoy with a cup of English breakfast tea.
