Step 1Crisp up the bacon in the oven or in a skillet. Oven is better for large batches. If you're only cooking 4 slices it's faster to cook in a lightly greased skillet.
Skillet: In a frying pan, fry the bacon rashers for 2 minutes per side until crisp. I dry fried them but you can add a touch of olive oil or ghee if you prefer to prevent sticking. All depends on your pan. Drain on a sheet of kitchen paper.
Oven: Preheat the oven to 190 °C/ 375 °F. Line a baking tray with baking paper. Lay the bacon strips out flat on the baking paper, leaving space so they don't overlap. Place the tray in the oven and cook for about 10-15 minutes until golden brown. The time depends on the thickness of the bacon slices. When done, remove from the oven and set aside to cool down. Store any leftover bacon in the fridge for up to 4 days.
