Hang on!
In the days when NZ was renowned for its clover honey the flavour of the manuka interloper was disliked enough that it is said (this may be an apochryfal story) that a beefarmer arriving at the docks was so disgusted with the price offered that he dumped it in the harbour.
It was only the chance discovery of the healing ability of methylgloxal that manuka turned into a global sales success. JBM is right that although medical-grade manuka has powerful healing abilities, it has not been shown (AFAIK) to have the same effect when eaten.
The taste does not recommend it either, but even if it had superlative flavour there's no justifiable reason, given current energy prices and awareness of environmental footprint, to import, sell or want honey that must travel 3,500 miles.
Ivy, on the other hand, is a marvel of taste. One year I extracted enough to sell at market, and I recall the pleasure of a customer describing it as tasting like Christmas.
Don't try, it sets like concrete.
Scrape the combs and honey back to the foundation with a spoon. When the colonies contract (not yet, probably) they'll take anything they perceive outside the nest, into the nest.
At this point you can put the ivy into a box feeder and let them clear it out. If you want to soften it, add a little water a day before and mash it, but no sooner because it may ferment.
Alternatively, soak the super in water for a few hours (yes, the whole box) and put it on top of a crownboard with a small access hole.
