Talking about slow cookers, I’ve been looking at some modern ones on the Argos website. The odd thing is they seem to use more electricity than the Tower models from quarter of a century ago.
In the mid-1980′s Tower had three models and they had the following power ratings:
Compact: 55w (I have this one)
The marketing of these centred around the fact that they used about the same amount of energy as a light bulb (100 watts).
Still going strong after nearly 25 years (and doing a chicken stew): Tower Compact slow cooker
The stainless steel Cookworks is rated at 160w-190w (and a real bargain at just £9.98 currently).
Do these slow cookers consume energy the whole time? Or does a thermostat turn them on and off occasionally to maintain the temperature? If so, the wattage given is a maximum and doesn’t tell the whole story. My 25-year-old 55 watt compact model seems to stay on permanently.
You might expect slow cookers to be even more energy efficient these days but it looks as if that may not be the case. I wonder if it’s because most modern-day slow cookers have a glass lid rather than the ceramic lids that are to be found on the old Tower models? Style over function and efficiency?
By the way, if you like stews and casseroles and haven’t tried this method of cooking, you are missing a treat. Cheaper cuts of meat turn out succulent and, whichever slow cooker you choose, it will use much less electricity than a standard oven, which may be rated at something like 2,500 watts.
