Chef'N® Sweet Spot Ice Cream Maker 5 "Worked beautifully, even in heatwave temperatures" Jo 23 June 2017 This is a really good product which does what it promises to do. I bought one a week ago, just as the June heatwave was hitting, and wondered just how effective it would be when the thermometer was hovering around 90 degrees. Answer: delicious ice cream in little more than a minute! It stayed cold enough to make a further 2 individual batches of ice cream and 2 of frozen yogurt (really lovely texture) - might have done more, but we'd eaten our fill by then. I made the vanilla recipe and would reduce the sugar by about 20% next time.
