I am a fan of electric frothers having owned one for two years and using it twice a day. To be specific, this one from Amazon originally purchased for £25. I remember Lidl selling something very similar for around £20. My only complaint is that the lid doesn't prevent milk for leaking out the top, so I am careful not to overfill it now. The reviews of the Asda George one don't look encouraging as it seems the temperature sensor is set too low or is often faulty. There is also mention of a black coating that wears off, so perhaps not the best quality. I would avoid the overpriced Bodum plunger frother. I have managed to break three Bodums already due to the ridiculously fragile glass (and I consider myself careful). The electric ones are brilliant as you don't have to heat the milk as a separate step. They are also great for reheating cold coffee to a comfortable drinking temperature without ruining the taste.
can it make hot chocolate?
You could give the milk a quick blast before you pour into the frother but we wanted a 2in1 frother/milk warmer hence the reason why we originally considered buying it. Our manual plunger frother is similar to the one in the link below (we consider it a good investment as ours is still going strong after a few years use). A quick blast in the microwave beforehand followed by pouring into the frother and plunge away (y) Short of investing in an expensive barista machine at home, i would say its the closest we have got to creating a coffee shop latte. horwood.co.uk/items/eating-drinking/tea-coffee-1/coffee-preparation/judge-coffee-milk-frother-150ml.htm?productid=1624&gclid=Cj0KCQjwmIuDBhDXARIsAFITC_4x8p-9lPFD5vMSxz0S17u5ZDaQjEmZfcBBXjat2iCbU80_9lk8CegaAtEKEALw_wcB
Use a Bodum; easy to clean and you can either heat before or after frothing depending if you want a sort or hard foam. You chose the temperature. I happened to find one at a local Lidl that had just opened (when I went to have a look at what the fuss was about) and it was £10, which is the lowest that I have seen. Amazon is good for the reviews https://www.amazon.co.uk/Bodum-1446-01-Latteo-Frother-Borosilicate/dp/B000BZ6BXE
I have this. Im not sure why someone said it takes five mins as mine is much quicker than that. I like mine and for 16 quid I consider it a good buy.
