S Curve

The S Curve is an Old-school style of roasting. It’s a great style and unfortunately, has been left behind many years ago as the specialty industry abandoned it. It still has merit and essentially looks to start the roast with a modest amount of heat and let the curve slowly roll into the Maillard phase where heat is then applied toward the back. In some respects, an S curve can be viewed as a pull-up front, with a ramp back.
