So I have been trying to make everything I eat from as scratch as I can (did that even make sense? Like I made my own pasta last night from flour, but I didn't make the flour as I do not have the right tools for that yet, but hope to one day just purchase grains and make it myself). Last night I made some 'beef' stroganoff based on a recipe that calls for fake sour cream. Normally I would use tofutti, but again I am trying to make everything and cut out as much processed stuff as I can, so I tried making tofu sour cream myself. And it worked okay (my recipe was 1 cup tofu, 2 Tb lemon juice, 1 Tb oil, 1 tsp vinegar) but it did not give the dish the sour cream like tartness or whatever it would normally (I am really not a sour cream fan, and this is the only thing I ever use it for). Now I looked in the recipe index and the sour cream recipes are varied, such as add more vinegar, add something sweet, add soy yogurt (which I don't really want to do). Does anyone have any recipes that would work well in this situation? The rest of the strognaoff recipe is some tvp, onion and garlic, some soy sauce, and some vegetable stock. Thank you very much for your help!
