Caramelised Red Onion Tart Tatin

This makes an unusual carbohydrate component for a meal — so you can skip the potatoes next time you’re getting the Sunday roast ready. It’s equally delicious served simply with a salad in summer or with some soft goats’ cheese crumbled on top once you remove it from the oven. I’ve found the best pan to make this in is a 30 cm (12 in) non-stick ovenproof pan. Although it’s also lovely made as individual tarts in small blini pans — you’ll need to make four of those.
