Why Did My Fudge Remain Smooth After Beating?

Our answer

Nigella's Vanilla Fudge is a traditional fudge recipe that is made by boiling butter, milk, condensed milk, sugar and golden syrup to soft ball stage. The fudge is then beaten as this makes the fudge slightly crumbly rather than chewy. Beating the mixture encourages the formation of small sugar crystals, which leads to the crumbly texture. The crystals may not be noticeable in themselves but the fudge mixture will thicken and turn from shiny to matte in appearance. When it sets, the fudge will be slightly crumbly when cut and should melt in the mouth.

It could be that there was an expectation of large sugar crystals rather than smaller ones. The beaten fudge will still look quite smooth and you will not notice large crystals when you eat the fudge. If the fudge is very soft and slightly chewy then it is possible that it did not quite cook to soft ball stage and next time the mixture should be cooked to a slightly higher temperature (soft ball is 112-116c/235-240F and a sugar or candy thermometer can help). Otherwise it could be that the fudge cooled too much before it was beaten. The mixture will thicken naturally as it cools and beating it enough once cooled is more difficult. Let it cool for a few moments but not for too long.
