 French onion gratin because you fancy four to five Spanish extra-large onions. Don't use sweet onions There's too much sugar in them. They'll turn to mush. Slice into half moons like that. Don't cry. Half a cup unsalted butter. Add the onion, fish or salt, pepper, cradle the heat between medium and medium low. Two tablespoons fresh thyme, saute until uber tender 30 minutes. Half a cup cognac. Don't reduce it all the way. We want the flavor. Homemade beef stock. Eight cups. Bring it to a gentle bubble. Reduce to a simmer. Ten minutes. Stay old baguette. Slice into half inch rounds. Butter the toast. Season, push yourself, even your bread. Into the oven 375 degrees until toasted. Broiler. Take a big fat garlic clove. Rub the toast. Little bed of cheese. Toast. Pour cheese. Under the broiler until melted and above it. Three to five minutes.
