Remove the stems from the gooseberries and place in the blender with the syrup, lime juice and mint leaves.
Bring the pureed mass with the preserving sugar to the boil and boil for about 4 - 5 minutes. Fill everything into jars, close and let cool.
You should dose the mint yourself depending on the desired intensity, depending on how strong you want the taste to be. I have Swiss mint and it tastes like a hint of mint.
