I make Rosehip syrup but it has a cloudy appearance. How does one clarify it?
Commercial varieties are crystal clear; how do they do it?
wash the hips well, pull off the stalks and put them in the grinder whole, then add the resulting mush to a pan of simmering water. They will mush up very easily and in no time you will have the sticky goo of seeds and what fruit flesh there, is floating in the pot. Simmer gently for a while and add plenty of sugar or honey (1lb of sugar per 1lb of fruit) as well as any spices you might like, such as ginger, cloves or cinnamon. Simmer until it reaches the desired consistency. Longer simmering makes it thicker, so it can be used as a marmalade spread. Shorter simmering leaves it a more syrupy consistency. When it is ready, pour it through a jelly bag and let it drip into a measuring container or jar. Fill into sterilized jars and close tight. Unopened they will last as well as jams do, but once opened they should be stored in the fridge and eaten within 10 days.
