Café du Monde's order since 1862: dark coffee blended with roasted chicory root, mixed half and half with hot milk, with a plate of beignets under powdered sugar.
40 g (1/2 cup) dark-roast coffee and chicory blend, ground for drip
500 ml (2 cups) water
300 ml (1 1/4 cups) whole milk
Sugar to taste
How to make it
Brew (5 min): Brew the coffee and chicory strong in a drip machine, French press (4 minutes) or pour-over. The chicory makes it dark, smooth and slightly bitter.
Scald the milk (3 min): Heat the milk to just below a simmer, until steaming and with small bubbles around the edge. Whisk or froth it a little if you like.
Pour (30 sec): Pour coffee and hot milk into each cup at the same time, from two jugs, in equal amounts.
Serve: With beignets or any fried dough dusted thickly with powdered sugar.
Tips
Chicory was a stretcher for coffee during shortages; it stayed because New Orleans liked it.
Over ice, it becomes the city's frozen café au lait; mix in a little condensed milk.
Can't find the blend? Mix 3 parts dark roast with 1 part roasted chicory granules.
