Roasting questions
What is the difference between roasting and grill marking?
Roasting chars the whole surface, usually to loosen the skin for peeling and give a fire-roasted flavor. Grill marking puts distinct char lines on sliced products for appearance and aroma.
Which products can be roasted?
Peppers and chiles, eggplant, onions, zucchini, tomatoes and other vegetables; grill marking is used on zucchini, eggplant, peppers and prepared foods.
What fuel do the roasters use?
Natural gas, with burners designed to mix gas and air for a clean blue flame. Automatic ignition shuts off gas if the flame is lost.
Can you build the complete pepper line?
Yes: feeding, stem cutting and coring, roasting, peeling, inspection and freezing or packing. See peppers & chiles.
