To make pitta crisps, heat oven to 200C/fan 180C/gas 6. Mix together 1 crushed garlic clove and 2 tbsp olive oil. Cut 4 pitta breads into strips, place on a baking sheet and drizzle over garlicky oil. Turn to coat well, season and bake for 5 minutes until lightly browned and crisp.
Alternatively baby new potatoes work very well
A good gratin should be cooked for a long period of time at a low temperature. This will leave the potatoes as soft as butter while allowing them to hold their shape. This dish actually improves when made in advance and reheated.

Upside down tarts have been made for years in France beginning with the Tatin sisters. Normally they are made with apples. This onion version makes a great Christmas recipe. Should you struggle to find shallots, baby onions or onion slices work just as well.
