My rosehip and haw went a bit wrong, because I put the haws in with rose hips to stew, and they were red when I added them and bright green BB pellets by the time i tried pushed them through the seive.
The rose hip reciepe I was using was:
Remove flower part of rose hip and then simmer for twenty minutes or the fruit is very soft.
Push fruit through fine sieve or jam bag/net and add it back into cooking liquid. [from experiance ware gloves if using am bag as fibre glass like hairs irrate hands]
Add 1lb of sugar to every 1 pint of liquid.
Return to stove to thicken and disolve sugar on low heat.
Alot of reciepes ask for more than one sieving just make sure the hairs are no longer in there. Some people also deseed before cooking , but this very labourious, and gloves need to be worn.
Next time I try it I will add the haws as a cooked pulp when ther sugar is added.
I will try apple fruit leather, but the apples I aren't to sweet so it might be mixed with blackberries.
