I am a chocolate lover and recently figured out I have to completely remove milk from my diet (due to problems with casein). I figured I can make my own milkless milk chocolate from dark chocolate by adding soy milk and... thickening it all the way back to solid form.
Now the problem is normally the way I'd approach it would be adding parts of liquid milk and parts of powdered milk to end up with good enough consistency for a chocolate block.
But I can't use powdered milk for the same reason I can't use liquid milk. I realize there are vegan alternatives to powdered milk like soy powder or coconut powder but those are really hard and expensive to get in Poland.
What can I use or do to create my own milk chocolate from dark chocolate with easily purchasable ingredients?
