Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker. A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 °F ...

Tomato paste. Tomato paste is a thick paste made from tomatoes, which are cooked for several hours to reduce water content, straining out seeds and skins, and cooking the liquid again to reduce the base to a thick, rich concentrate.
