I have owned several slow cookers over the years, and as a result have come up with a short list of essential and desirable features. The Breville VTP105 ticks almost all the boxes.
Straight out of the box, it has an easy-care black finish that doesn't show every single fingermark (unlike brushed stainless steel). The glass lid allows you to keep an eye on the food as it cooks without releasing valuable heat and steam. The only control is a four position rotary knob on the front, with Off, Low, High and Auto settings. This latter setting is not very common - slow cookers usually have only High and Low settings, sometimes with the addition of a Keep Warm feature. On the Auto setting, the cooker starts off at full power, then cuts back to Low power after the first hour or so. This is a tremendously useful feature, and one that I was specifically looking for when I made my purchase.
The first essential of a slow cooker is that it should really be a s-l-o-w cooker - there's little point in having a slow cooker that is really just an electrically heated boiling device. The VTP105 performs admirably in this regard - although I have seen user reviews elsewhere that complain it cooks too fast. One of the first things I did on receiving my new cooker was to try a little test with a thermometer and a plug-in power meter. I half filled the cooker with plain water and switched it on to Auto. Power draw was around 280 Watts as it heated up, then, after an hour or so, it automatically cut back to about 180 Watts where it stayed for the remainder of the test. It took about 3 or 4 hours to reach 98 degrees C, where it remained on a very low simmer until I terminated the test. Textbook slow cooking.
Of course, the proof of the pudding is in the eating. With this in mind I set about cooking a family favourite - a whole roast chicken slathered with butter, thyme, paprika and lemon. With the VTP105 set to start cooking while I slept at 6am via a plug-in timer, I retired to bed. I woke to a glorious aroma from the kitchen, and at 2pm served up a superbly moist and tender roasted chicken. It really doesn't get any better than this, in my opinion.
The stoneware cooking pot is not dishwasher safe according to the User Manual (although the glass lid is OK). this is really the only criticism I have of the VTP105 - I like to chuck everything in the dishwasher after dinner!
The capacity of the VTP105 is quoted as 4.5 litres. This is spot on for a family of 4/5 people as the slightly smaller 3.5 litre models can struggle to accomodate a Medium sized whole chicken, while the significantly larger 6.5 litre cookers are better suited to large families and/or "batch" cooking.
If I was being really, really picky, I would have liked to see a detachable mains lead. But that, and the non-dishwasher safe pot are my only criticisms of this cooker. For £26, you really can't go wrong.
