Same.
I dont do much customization, but the endevorOS community edition has decent defaults.
Just working cleanly with tiling feels so good. You dont have to use the mouse to move all the windows around. But if you hold the super key, you can just drag windows around to make a perfect layout. But often than not, i just want 2 windows side by side, with no wasted space. Done.
Going to be tough to answer any of these questions with authority, as I do not bake much, and nothing I’ve ever baked has used sour cream. My experience with sour cream substitutes is just slipping it on top of tacos/fajitas/burritos. And for that purpose- it works just fine.
Regarding using four cream as a thickener for soups- any thickener is going to work. Another poster suggested coconut cream, that works well for me. Adding starch of any kind will also work to thicken soups. If you’re looking for extra protein: blend up some cooked white beans, or silken tofu works really well for this too.
Now for your question #2: I don’t know if I’ve ever encountered vegan sour cream with oat or almond bases, but I know when comparing oat/soy/almond milk— the soy is the only one with protein and fat content. Oat and almond milk tend to have very little nutrition, and are mostly cloudy water (exaggeration). So I tend to use unsweetened soy for most my cooking. Your mileage may vary.
Good luck!! And remember that you don’t have to only cook from physical cook books- the internet is LOADED with good vegan recipes. Do some experimenting. Don’t be discouraged when something doesn’t turn out, it takes a while to get the hang of using so many new ingredients!
