To be forward and clear, here is a fact: heating honey does cause a loss of its aromatic properties. Here is another fact: cooking the honey to a boil and caramelizing some of the sugars replaces those lost aromatics with a whole new set of possibilities.
It's time to talk about bochets. I do see quite a few posters talk about wanting to make one but haven't gotten around to it yet. Bochets require no more or less skill than preparing a traditional mead must. There are more steps, but assuming you can cook spaghetti, you can overcome those new challenges.
Step 1. Grab a big pot (with a lid).
We will be cooking the honey to a boil. The honey expands to roughly 3-5 times its original volume. The honey will also move more freely as it heats up, almost like water before coming to a foamy frothy boil.
Step 2. Put Your Junk in the Pot.
By "junk" I mean "honey" of course. Honey selection is a bit different with bochet making, as those original flavors and aromas get changed out with new ones. Now is not the time to use your meadowfoam and tupelo stash. However, this doesn't mean go use cheapo depot honey. A basic wildflower or clover honey will work fine.

Step 3. Heat Up the the Pot.
Heating up the honey is the new part of the equation. As the honey boils and foams, it will get darker. It will also throw off a few different aromas. How long you heat your honey depends greatly on the power of your heat source, so I can't provide a timetable for certain flavors or colors. However, in my experience, there is a range of aromas that get created in a specific order, and each of those create different flavors down the road. Remember that the aromas you are smelling are no longer in your meads.
The first aroma that comes in the boiling process is a kind of nutty one. This is very early in the process and is rather fleeting. The flavor contribution in your final mead is a thin sharp sweetness. I don't find it too enjoyable, so I usually continue cooking. Next there will be a reduced amount of aroma production.

When the aromas start coming out again it will be a warm toasted marshmallow. The marshmallow aroma is here to stay, and will continue to get stronger while adding a more burnt marshmallow characteristic as cooking goes on. Just going 5-10 minutes into this stage is a level I have found where I like to be at. The honey isn't always as dark as it could be, but the flavor profile is that of caramel and some burnt sugar.
The honey can continue to cook to a deep ruby black. If you do, there will be harsh burnt sugar notes early in the aging of the mead. These age out into a more burnt cherry kind of flavor.
With all of my bochets, time has done nothing but amazing things for them.

Step 4. Cool Down the the Honey.
Your honey is now a molten mass of sticky goop. Don't let it touch you, or you'll be in a world of hurt since the hot liquid won't just run off you. Remember that lid? Now we're going to use it. To cool the honey down quickly (we need to or it will keep cooking), I add about a cup of HOT water to the honey. When I add the water, I put the lid on quickly after pouring it in. This is because the honey reacts violently to the rapid change in temp and shoots the molten honey upward. If you use cold water the reaction is even more violent. Once it calms down I add another cup and repeat. After 2-3 additions, the honey stops reacting and cold water can be added.

Step 5. Clean up.
Clean up is usually easy, and has always been easy for me. Some honey may get caramelized to your spoon and pot. This can be dissolved in hot water. If you clean quickly, you shouldn't have any issues either, but using a junky pot can be reassuring.

Everything else is just regular mead making (nutrients and aeration, etc). When it's done, depending on your original darkness, your mead will be a deep copper to dark ruby.
