Ingredients You’ll Need
| Ingredient | Quantity | Notes |

| Single or double cream | 150–300 ml | Choose richness level, single for lighter option |

| Grated cheese (cheddar or gruyère) | 100–150 g | Adds sharp flavor and golden crust |
| Salt and pepper | To taste | Essential seasoning |
| Optional: garlic or nutmeg | To taste | Adds extra warmth and aroma |
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat oven to 180 °C (160 °C fan)/350 °F. Grease an ovenproof dish with butter.
Step 2: Cook or Grate Potatoes
Either lightly parboil peeled potatoes until just tender, or grate them raw for quicker assembly (both methods are used in Mary Berry’s variations)
Step 3: Heat the Cream
Gently warm cream with a pinch of nutmeg and seasoning—avoid boiling to preserve smooth texture.
Step 4: Assemble Layers
Layer potatoes in dish, pour cream evenly, and sprinkle cheese over each layer. Finish with cheese on top.
Step 5: Bake Until Golden
Bake for 45–55 minutes until the top is crisp, golden, and bubbling—a sign it’s perfectly cooked
