I first discovered sweet limes when we lived in India. They have a sweet/sour flavour, almost a cross between a lime and an orange, and the juice is sweet enough to drink without the addition of sugar. They also make fantastic marmalade and pickle.
So for my sweet lime marmalade I followed the standard marmalade making procedure, but only used half as much sugar as usual. The end result is a murky olive green, nothing like the day-glo lime green of the commercially made product, but it tastes so much better! It’s surprisingly tart (considering the fresh fruit isn’t) and actually tastes of real limes – I love it.
Off to pick some more now to make a hot pickle to go with curry.
