The cavalry originated in the countries of the ancient world, in the regions where horses were raised on a large scale. Before the appearance of the cavalry in the armies of Egypt, China, and India, horse-drawn war chariots were used.
Roasting is cooking food, from meats to vegetables, with fats so that they have a brown and glazed exterior and a moist flavor. Baking muffins. Baking is the term used for cooking foods such as bread, potatoes, apples, etc. in dry heat in an oven.
Pan searing = High heat, short cooking time, not a lot of oil used. Pan fried = Medium-high heat, medium cooking time, more oil used than in searing. Pan roasting...I've no idea how one can roast with a pan (at least not over an open flame), since open flame cooks food faster than just heat (oven) and it cooks too unevenly for roasting something.
