Make your own yoghurt! It is so simple and all you need is whole milk, plain yoghurt (that you can take from your previous batch) and whatever you want to put inside to give it more flavour (fruits, syrop, sugar…) You can follow any recipe online!
It is not necessary but if you find it easier you can use a yoghurt maker. You will save so much waste and money compared to these individual plastic packaged yoghurts sold everywhere. Homemade yoghurt is colorant free, additive free, 100% natural, zero waste, cheaper and so delicious! Easy!
