Use of traditional copper sauteuse pans
A sauteuse pan is a very versatile pan. If you have no lid, it's a great pan for sautéing and browning. With a thin layer of oil you can cook vegetables, scallops, latkes, etc. If you have lids that fit you can braise in these. You can also use to cook pasta, stews, etc. Copper is good conductor, so these should heat evenly. I also sometimes use a pan like this for pâte à choux. They sound like really nice pans.
