Beef tartare with goat's cheese and caramelised onions

I thinly slice beef.Then dice.I chop with a knife, fine but not too fine.I chop desalted capers.I mix meat, capers, salt, pepper and extra virgin olive oil in a bowl.I add grated lemon zest, cover and refrigerate to absorb flavour.I mix goat's cheese with salt, pepper, extra virgin olive oil and grated lemon zest.I mix well and refrigerate.I make caramelised onions. I thinly slice onion with a mandoline, add oil and 2 tablespoons brown sugar and heat.I add salt and pepper and soften. I add vinegar and finish cooking.Onions should caramelise and dry. I cool.Everything is ready to assemble.I divide meat between two portions, pressing into a serving ring on the plate.I divide goat's cheese too.I add caramelised onions.I carefully remove the ring and finish with oil.
