Just as an aside, for yet another batch, I took a large jar of two-year old damson jam, added about fifteen chillis, (previously softened in garlic and chilli oil), added a small amount of the jam to a blender, chucked in the chillis, whole, and zapped the lot...
While it's now the consistency of HP sauce, it really does 'grow hair' I can tell you!
It won't lasy long enough to worry about preseving, as Elder Daught is on the warpath for a refill of the last lot...
