You will need:

Combine together, either by hand or in food processor:
(use the pulse action if you have one)

150gms of butter
1/2 cup of caster sugar
1 cup of fine polenta
1/2 cup of plain flour

Then add, one by one, 2 eggs strirring until fully incorporated.

Finally stir in:

Zest of 2 or even 3 navel oranges.
This can be grated but for better effect peel or use a zester, and then chop the zest into about 1cm strips and add up to 100gms of cooking chocolate bits or finely chopped chocolate.

The mixture will be very moist wrap in cling film and chill in the refrigerator.

To cook:

Preheat oven to 190c.

Place teaspoons of mixture on lined baking trays - leaving space to spread.

Cook for about 10 minutes, maybe less - until edges of biscuits are tinged golden.
Rest a few minutes and then gently place on rack to cool.

Makes about 30/36 biscuits
