Go out and buy a package of fresh yeast!
Dump it in some warm water about 4 AM Sunday morning. It will start foaming in about 15 minutes. Stir in flour and salt. Knead by hand, on a floured board! Let the dough rise in a covered oiled bowl for an hour. Punch it down and knead it again. Form it into baguettes and put it in the oven. Sprinkle a little water in there so it steams and makes the crust all brown and crunchy. Take it out and serve it warm with good butter and fruit preserves and strong coffee.
Oooooooo, you’re in PARIS! I envy you.
