Autumn has officially begun. In the US this means pumpkin-spiced everything. In the UK, pumpkin puree can cost upwards of £4 a tin, so no thank you. I've found you a substitute and it is GAME CHANGING for autumnal baking. It looks and tastes the same, costs 1/3 of the price AND is packed with fibre and antioxidants. No more pumpkin-spice fomo.
