Bake for 40-50 minutes. The crème brûlée should be set, but still a little jiggly in the middle. Remove the ramekins from the roasting pan, allow to cool to room temperature, cover with plastic wrap and refrigerate for at least 2 hours, and up to 3 days.
That looks like a delicious dessert for the least amount of prep and bake time.
Perfect for family nights and guests.
A cheap alternative too!
I wonder if a few drops of vanilla essence or vanilla bean paste would hinder your recipe?
