Not to rain on the parade, but plant milks are astronomically expensive compared to dairy milk. Plant milks need to become way cheaper than currently 5x the cost for me in India. There is only import, no local making.
The one I am tasting right now, is a Thailand import. Oat milk is absolutely the closest of plant milks to replicate milk taste, and I can see why the only difference is due to lactose. Mixing a couple teaspoons of powdered sugar makes it sweet fantastic, and the only issue I see is cost.
Making oat milk is a really simple process & to make it more like commercially available products, you can add various other ingredients such as xanthan gum to bind it as well as various things for flavour such as a small amount of cinnamon.
Nobody has the time to do that. I am not going to put that much work (and that is not laziness) in manually making oat milk when I have a million other things to think, manage and do. This mindset will absolutely never help adoption of more vegan practices. I am all for inching towards less meat/animal related foods but it has to be viable, optimal and must not be a nutritional compromise (protein combining with one compact meal is fair).
That surprises me, since I'm told (a large part of) India deems cows holy and over here, the cheapest milk is from cows kept under inhumane conditions...
Cows are also kept under "humane" conditions. Amul is the largest dairy of Asia and the second largest behind Danone globally, and they are a socialist cooperative of women.
