If you love classic ginger biscuits with crackly tops, crisp edges and a chewy centre, these sourdough ginger cookies are about to earn a permanent spot in your recipe card collection. They’re warmly spiced, deeply flavourful and made with sourdough starter discard for extra chew and complexity.

Instructions
To make browned butter, place the butter in a small pan and heat it over medium heat. The butter should melt, then foam, and finally brown. Leave the butter to cool down slightly.
Add both brown and caster sugar to a large mixing bowl. Pour the browned butter over the sugar, and using a handheld electric mixer, beat the mixture for 2-3 minutes until the sugar starts dissolving (it will still be grainy, and it's ok).
Add an egg yolk and whisk again for approx 2 minutes.
Add the sourdough discard and mix with a balloon whisk until combined (you don't want to use an electric mixer here as it will promote gluten development).
In a separate bowl, mix flour, baking soda, salt and ground ginger.
Add the dry ingredients to the wet ingredients and mix just enough to combine.
Finally, add the chopped stem ginger and mix to distribute them evenly throughout the sourdough cookie dough.
Cover the dough and place it in the fridge for 4 hours.
Preheat the oven to 180°C (350℉). Line two large baking sheets with parchment paper.
Divide the cookie dough into 8 even pieces (about 60g each) and shape each into a ball.
Place the balls onto the prepared baking sheets, leaving plenty of space in between them
Bake the cookies for 12-14 minutes. The cookies should have browned crispy edges, but the centre should still be a little soft and puffy. As soon as you take the cookies out of the oven, drop the tray from 20cm height onto a kitchen worktop – this creates that signature cracked tops.
Leave them on the tray for 10 minutes to firm up, then transfer the cookies onto a cooling rack.
Notes
Stem ginger is widely available in the UK (sometimes called preserved ginger in syrup), but can be harder to find in regular grocery stores in the United States. The best substitute is finely chopped crystallised (candied) ginger — use the same quantity. It will be slightly less juicy and a little firmer, but still gives that warm, spicy bite. Avoid fresh ginger as a direct substitute — it’s too sharp and lacks both sweetness and tenderness these cookies rely on.
