Presser Cooker Vs. The Gastrovac

trev_teich

Can similar results be obtained with a presser cooker as the gastrovac? I understand that the vacuum allows to be able to precisely control the temperature of when liquids boil, but is there a noticeable difference between pressure cooked stocks, fruit, etc, for $5,900? I've only seen two kitchen own them and one never used it. The price tag being a reason I couldn't do my own testing.

No, do not do the same thing. A pressure cooker will cook food at temperatures well above the standard boiling point of water. This can greatly speed cooking. A Gastrovac uses a vacuum pump to lower the boiling point of water. Clearly food cooks faster at higher temperatures and slower at lower temperatures, so a pressure cooker doesn't do the job of a Gastrovac and vice versa. Personally, I wouldn't spend money on a Gastrovac.
