O’boy has been on the market since 1959 and is the most popular chocolate drink powder in Scandinavia – a favourite with children from northern Norway to southern Denmark. The debate rages on how to mix it for optimal taste and texture – there is no definitive answer so we suggest you try it yourself. Milk first? Powder first? Cold or hot milk is up to you – we also like sprinkling it on ice cream or using in milk shakes.
