Yoghurt making is very easy. If you know you are going to eat it regularly then get a yoghurt maker, a cheap one will do they all work in much the same way (don't bother with the one that you need to buy a special starter for). Once you have made one batch you can then use a little of it to make the next.
I made some yoghurt with UHT goats milk recently, it turned out very runny so I strained it through some clean kitchen paper overlaid with a muslin square for 24 hours and made it into a cream cheese, to which I added chives from the garden.
