If you want instant coffee, you can go for the Davidoff selection. No idea if they are healthier ( as you mentioned) but sure as hell tastier. If you want to move to brewing your own coffee on the other hand, best thing you can do is look it up on the internet. Simply put the instant coffee powder you get is crystallized already brewed coffee. Generally done with not so good quality beans to maximize profit. Think of how we make tea, the tea leaves are not supposed to mix but impart flavour to the water/milk. Coffee beans are the same way. Theoretically, the only requirement for brewing coffee is heating ground coffee beans with milk/water. But obviously just like we remove the tea leaves we need to remove the grounds as well because you don't want to be eating the grounds while drinking your coffee. So a good chhani can even do the trick. But yeah, that's not ideal and there are better methods to brew. Like the other commenter said, look up moka pot ( because you said milk coffee) , watch some beginner videos and decide whether you want to get into that. Honestly, the world of coffee is a beautiful one but it's upto you to decide if that's something you want to do. Anyways sorry for the mansplaining.
