["Preheat oven to 400 deg F/200 deg Celsius Have ready a tart plate or dish, not too large.", "Peel the onions and cut into thickish rounds, about 1/4 inch thick. It's not too important, but the rounds should not be too thick to soften properly.", "Heat the olive oil in a pan to quite a high heat. Add the onions. They'll break apart -- no worries. Let them fry over high heat for a few minutes. Then sprinkle over the balsamic vinegar, and top with the brown sugar. (Any brown sugar will do).", "Before you turn down the heat, turn over the onions once. Then lower heat, put on a lid, and let stew slowly for about 15 - 20 minutes.

Tips for the best results

Read through all the steps once before you start and measure out your ingredients first — it makes everything go more smoothly.
Preheat the oven fully and bake on the middle rack for the most even results.
Check for doneness a few minutes early — a toothpick in the center should come out with just a few moist crumbs.
Let it cool before slicing so it sets properly and holds its shape.
Store leftovers in an airtight container in the fridge and enjoy within a few days.

Variations & substitutions

Brown sugar instead of white sugar adds a deeper, more caramel-like flavor.
Leave out the nuts to make it nut-free, or swap in seeds for a similar crunch.
