Measure 200g Self Raising Flour and 100g Salted Butter into a mixing bowl. Cut the butter into smallish pieces as you add it.
Use the pulse function to blitz the mixture until the butter is evenly distributed and it looks like breadcrumbs. This should only take 10-20 seconds or so.
Measure in 100g Sugar and ¼ tsp Sea Salt Flakes.
Blitz again using the pulse function just once or twice to distribute the sugar. It doesn't need cutting into finer pieces.
Your crumble topping is now ready to use!
