Recipe video above. This is the crumpet recipe released by Warburtons, the UK's largest commercial maker of crumpets! The batter is extraordinarily easy to make, but cooking them may take practice to get the temperature right for your stove. But if you've nailed pancakes, you will nail crumpets!Double rising agent is the key here for the signature holes - baking powder PLUS yeast. Just one doesn't cut it, and baking soda doesn't work as well.It's alarming how much time I've lost watching the bubbles pop...it's mesmerising!!!
