3 cups ground almonds
1 1/2 cups sugar
3 egg whites
1 tsp ground cinnamon
Pre-heat the oven to 150c. Line a tray with baking paper.
Mix all the ingredients together
Roll small amounts into balls and place on the tray. These biscuits don't spread when they cook, so you can put them quite close together.
Bake 20 - 30 minutes. The longer you bake them, the crunchier they become. Dad likes them to be a bit chewy in the centre.
