 The most luxuriously simple French onion tartetin, inspired by Le Crusade's new Rhone color. It has the most gorgeous shade of plum and it's perfect for the holidays. After prepping the short crust, we're gonna cut our onion, caramelize some of them with some wine, beef stock, seasonings, butter and balsamic vinegar. Trust me, the flavor profile here is unreal. Then we're gonna add some butter and sugar to the pan, add the onions, brown them for a little bit. Gonna fill in the gaps of the onion with the caramelized onion, add some Gruyere, the crust, we're gonna bake until nice and golden, then we're gonna make the richest and most delicious glaze, full recipe in the caption. Flip it and take a look at this gorgeousness.
