I don't like chocolate bars they are too sugary sweet
Semi-sweet dark chocolate at home, is so easy to make with the basic ingredients being chocolate, honey and salt. Besides honey, thick black strap molasses and maple syrup are good sweeteners.
Take some cocoa powder and stir some apple juice into it until you get a thick result. Stir in some honey or maple syrup to make it more sweet. Add a pinch of salt. Let sit for 30 minutes so ingredients can meld into each other
You could also add raisins, figs, almonds, peanuts what have you. You can add some plain yogurt. I suppose you can work milk into this recipe for "milk chocolate" but I have never done it
If you buy squares of Baker's unsweetened chocolate you can shave off pieces, drizzle some honey or black strap molasses over them and eat. But the real way is to heat the chocolate and honey in a double boiler until it is liquid then pour that into a mold. I have done this a few times. A better way is to put the chocolate and honey in a Pyrex bowl, cover with foil, then put in a pot where it steams. Let it cool solid in that same Pyrex bowl
