Step 1

If you use sliced cheddar, cut it into 0.5 inch / 1 cm squares. If you are using a cheddar block, crumble it with your hands to the same size.

Step 2

Cover the cheese with a muslin / kitchen towel to prevent it getting dusty and let it sit in a warm, dry place for up to 3 days. You want the cheese to be completely hard and dry.

Step 3

Heat your oven to 200 Celsius / 390 Fahrenheit. Scatter the cheese on a baking tray lined with parchment paper and bake for 4-5 minutes until the cheese pops. To prevent it from popping all over your oven, place a second baking tray closely above the tray.
