1. Pre-heat the oven to 200c and line your baking tray with greaseproof paper or silicone.

2. Roll out the pastry into one large circle (around 35cm) or two smaller ones if you'd rather make two tarts (this is what we did, cutting around small plates).

3. Put the pastry onto the tray.

4. Peel the apples, then slice them thinly with a sharp knife (adults only!). Put them into a bowl as you go.

5. Squeeze some lemon juice onto the apple to stop it from going brown.

6. Put a thin layer of apples onto the base, leaving a gap of around 2cm from the edge.

7. Turn up the edges of the pastry all the way around so that it has a border.

8. Dot the butter around the top, sprinkle the sugar and cinnamon lightly on top and put it in the oven for around 15 minutes. Watch carefully so that it doesn't burn, and make sure that the bottom is firm and golden when you take it out.

9. Warm the jam in a pan and then spread over the apple. Eat warm.
