From David Lebovitz. I heard about Flo Braker from David Lebovitz' blog, and I’ve been baking a pick of her recipes. This one makes a slim, crunchy almond biscuit, shaped like some commercial ones you can get in the supermarkets.
My batch made about 70 biscuits, but Flo reckons on 80-90. This is a lot.
115g butter 300g demarara sugar (David cites turbinado for Americans) 1.5 tsp cinnamon 80 ml water 325g plain flour 0.
Rachel Roddy's Biscotti Adapted from Rachel Roddy’s Biscotti.
Set oven to 180C.
Whisk 4 large eggs with 350g caster sugar until thick and creamy.
Add:
500g flour (the linked recipe asks for 400g, but that is very hard to handle) 150g toasted hazelnuts 2 tbs olive oil pinch of salt 0.5 tsp baking powder 60g sultanas zest of one large orange Mix and form into 2 x 20cm logs, then flatten into 10cm wide.
Shortbread Based on: Felicity Cloake’s Perfect Shortbread.
Quantities doubled to suit the baking tray; makes 20 - 24 fingers.
Set the oven to 150C. Line with greaseproof paper one of those half baking trays with a raised edge (1cm).
230g room temperature butter 110g caster sugar Beat together until smooth.  Sift and add:
260g plain flour 80g rice flour/fine semolina Good pinch of salt Bring together as a dough, the press or roll out into the baking tray.

Unashamedly stolen and adapted from www.cookingforengineers.com - this is the Almond and Orange Biscotti recipe.
200g sugar 2 large eggs 80g slivered almonds 2 tbs orange zest (zest of half an orange) 1 tsp baking powder 1/4 tsp salt 250g plain flour 1/2 tsp vanilla extract 1/4 tsp almond extract Sift and mix flour, baking powder and salt; put to one side. Mix sugar and eggs, and beat until pale (take a couple of minutes with an electric hand mixer).
150 g unsalted butter 75 g light brown or demerara sugar 3 tbs golden syrup 250 g rolled oats 1 tsp ground ginger (optional) Melt butter and stir in sugar and syrup, then oats and ginger (if using).
Press into a 20cm square tin, or equivalent baking tray.
Bake for 20-25 mins at 180C/375F/gas mark 5 until golden at the edges. Cool for 15 mins, and slice.
You could vary the size of oats, and consider mixing a proportion of oatmeal instead of up to 50% of the oats.
Flakemeal biscuits, from Margaret Bates ‘Talking About Cakes’. I have never seen flakemeal available, but normal rolled oats or oatmeal produce excellent results.
220 g / 8 oz butter (2 sticks) 110 g / 4 oz sugar (4 tbs) 110 g / 4 oz plain flour (4 tbs) 275 g / 10 oz oats or oatmeal (3 cups) 1 tsp salt pinch baking soda Cream the butter and sugar.
This one comes from Mary Berry, and produces an exquisitely rich and squishy brownie.
340g/12 oz dark chocolate, high cocoa content preferred 225g/8 oz butter Put this in a bowl and melt over a saucepan of boiling water. Then add a small shot of espresso (2 tsp instant coffee and 2 tbs hot water if you can’t manage an espresso). Allow to cool a little before the next stage.
