A quick word on which honey to reach for. For baking and glazes, a milder clear honey or soft set does the job, because heat softens the finer aromas anyway. Save the bold heather honey for the things you do not cook - drizzled over a cheese board, stirred through cream, spooned onto warm bread - where you taste every bit of it.
One thing to know: heather honey is bold and aromatic and heat dulls it, so it shines uncooked - stir or fold it in at the end. Ivy sets hard and pale, so it loves to be melted into a hot drink or a tray bake.
