It's fairly common with kitchens to recess butt hinges entirely into the door, it's a time saver. I did it when I was building my own kitchen and my wife was getting impatient,
However I never do it on my solid wood furniture, then I always recess a hinge equally into the carcass and into the door stile,
I sympathise with anyone struggling to properly hinge solid wood cabinets. The sort of glib, happy face advice you get on the internet or from jig sellers seriously underestimates the difficulty of doing a good job. A properly hinged cabinet door has a perfectly uniform gap of about 1mm all around the door, it opens and closes without any trace of binding, and if it's inset then it sits perfectly flush with the face frame or cabinet sides. Achieving all that isn't easy. To begin with both the carcass and the door need to be absolutely true with zero twist or wind, and that takes some doing in itself.
The next problem you face is sourcing adequate hardware. With a good brass butt hinge you should be able to hold each leaf in a separate hand and feel no play when you wiggle them around. I've found
some sizes of hinge from Isaac Lord and Ironmongery Direct that meet that standard, but it's so hit and miss that I'm now digging deep and sourcing all of my hinges from Horton Brasses in the USA. The irony is that Horton actually get many of their hinges from UK manufacturers, but they apply a higher quality spec while UK retailers are chasing the lowest possible price so their stock just keeps falling in quality.
I could you walk you through the process for hanging doors, but it's quite lengthy and I need to get back to work. However, if you've got any specific question then fire away and I'll try and help.
Good luck!
