1 tsp salt

Cream Mixture: Place butter, cream and garlic in a jug. Mix until combined.
Preheat oven to 180°C/350°F (both fan and standard ovens).
Slice potatoes: Peel the potatoes and slice them 1/8"/3 mm thick. Or use a slicer!
Layer 1: Spread 1/3 of the potatoes in a baking dish (Note 3), then pour over 1/3 of the Cream Mixture, scatter with 1/3 of the salt, pepper and thyme. Sprinkle with 3/4 cups cheese.
Layers 2 & 3: Repeat for the 2nd and third layer, but do not finish with cheese on the top layer (will add later).
Cover & bake: Cover with lid or foil, and bake for 1 hour 15 minutes or until the potatoes in the middle are soft (use knife to test), it might take 1 1/2 hours. (Note 5)
